Is Development Determined in the Womb? Essay

Introduction animatenesscycle or lifespan ontogeny is the field in psychological science that studies how people change with time. These changes could be biological, including body changes and motor skills cognitive, including thought and vocabulary and psycho complaisant, including emotions, individualality and relationships with otherwise people. Life cycle exploitation starts in the uterus at conception and continues throughout the singulars life. Other st identifygic stages of development ar birth, infancy, adolescence, adulthood, old age and fin entirelyy death. though rough aspects of development whitethorn be strongly influenced by how the fetus develops in the womb, the brokers one receives from his/her pargonnts interact with the environmental factors after the one-on-one is born such(prenominal)(prenominal) as the nourishment one eats, p arenting, experiences, friends, family relationships, culture and school. All this help us understand the influences that he lp contribute to growth and development. Our genes are the bio-chemical units of heredity that get in each of us a distinctive human being.The genes we share rush us people rather than dogs or tulips. But might our single(a) patrimonial make-ups explain why one person is outgoing, another is shy, or why one person is slow-witted while another is new? Some developmental psychologists focus on explaining how our genetic background force out check out not only how we look, but to a fault how we be put one across, how we relate to others i.e. matters of personality. These professionals seek ways to identify how much of our potential as human beings is provided or limited by heredity. In this article well take a close set(predicate) look at how biological influences (genes) help shape individual development. Well win much about how genetic disorders stack rival ones psychology and development and overly how our experiences interact with genetics. Lastly well envision on wa ys to take care of a claw while in the womb and after to ensure they reach their maximum genetic potential.How biological Influences Determine Development.Development begins at that moment when chromo virtuallys in the sperm and egg cell join together in the fallopian tubes to form 23 pairs in an merely new cell called a zygote. Chromosomes are composed of molecules of DNA containing the genes. Genes are pieces of genetic material that control or influence features. It is these genes that leave alone soak up cell activity for the rest of the individuals life. A gene controlling some specific characteristic always appear in the same place (the locus) on the same chromosome in every individual of the same species. For modelling, the locus of the gene that determines whether a persons argument is type A, B or O is on chromosome 9. Genes also determine the nature and function of every cell in the body. For instance, they determine which cells testament ultimately become smash of the heart and which will become part of the vigours of the leg. It is the genes that establish how different parts of the body will function how quickly the heart will beat, or how much strength a muscle will arrive. The genetic instructions passed put down from both parents influence how an individual develops and the traits they will have.Combinations of genes from the father in the sperm and from the spawn in the egg cell create a unique genetic blueprint the genotype- all of the genes that a person has inherited-that characterizes that specific individual. The actual expressions of those genes that gouge be identified by directly observing the individual is the phenotype. The phenotype fire include corporal traits, such as height and disguise of the heart and souls, as well as non- sensual traits such as shyness, a high strung temperament or a thirst for adventure. Whether or not a gene is expressed depends on two different things the fundamental fundamental intera ction of the gene with other genes and the continual interaction between the genotype and the environment. The simplest genetic rule is the preponderating-recessive pattern in which a single dominant gene strongly influences phenotype.If a shaver receives a single dominant gene, for a trait from one parent, the childs phenotype will include the trait determined by that gene. In contrast, a childs phenotype will include a recessive trait only if she inherits a recessive gene from both parents. Eye color is one example of dominant-recessive genes at work. The gene for brown eyes is dominant and the gene for blue eyes is recessive. If one parent hands down a dominant brown eye gene while the other parent hands down a recessive blue eye gene, the dominant gene will win out and the child will have brown eyes. A persons sex is also determined in the womb. An individual inherits 23 pairs of chromosomes.Twenty- two of these pairs of chromosomes, called autosomes, contain close to of the genetic information controlling highly individual characteristics like cop color, height, body shape, temperament, aspects of intelligence and also all those characteristics shared by all members of our species, such as pattern of physical development. The twenty-third pair, the sex chromosomes, determines the childs sex. One of the two sex chromosomes, the X chromosome, is one of the largest chromosomes in the body and carries a large number of genes. The other, Y chromosome, is quite gnomish and contains only a few genes. Zygotes containing two X chromosome i.e. XX develops into effeminate and zygote containing one X and one Y chromosome i.e. XY develops into male.Genetic Disorders.Though development in the womb usually produces a normal infant, genetic instructions are not infallible and can go gain track at times. Sometimes when a sperm or ovum is formed, the number of chromosomes whitethorn divide unevenly, causing the organism to have more or less than the normal 23 chrom osomes. When one of these abnormal cells joins with a normal cell, the resulting zygote will have an uneven number of chromosomes. In every case, the result is some type of syndrome with a set of distinguishing characteristics. For example, level Syndrome in this case, the child has three chromosomes at the site of the 21st chromosomes alternatively of the normal two. This can result to mental retardation and abnormal physical development.How Interaction Between The Genes And The Environment Determine Development. Although genes play an big grapheme in human development, they alone do not determine who we are. It is distinguished to note that the environment an individual is exposed to both in womb and throughout the rest of his or her life can also impact how the genes are expressed. For example, exposure to harmful drugs while in womb can have a dramatic impact on later child development. Exposure to teratogens, which are noxious substances or other factors that can pick pren atal development can prevent the individual from reaching his or her inherited potential.For example, prenatal exposure to X rays can disrupt the migration of superstar cells, causing mental retardation (Schull, Norton, & Jensh, 1990). Environmental factors such as the food we eat, the air we breathe, the physical and social contexts we experience, our relationships and our continual ongoing interactions at work, at home and at play are necessary for a person to develop well. Heredity and environment work together to produce persons intelligence, temperament, height, weight, ability to read and so on. Height is a better example of a genetic trait that can be influenced by environmental factors. While a childs genetic inscribe whitethorn provide instructions for tallness, the expression of this height might be suppressed if the child has poor nutrition or a inveterate illness.Proper Care During And by and by PregnancyFrom the above information we can see that most of an individua ls characteristics, from sex, eye color, height, intelligence are determined in the womb because of the genes, great care of the foetus is important to ensure the development is not impaired. Genetic codes are not sealed signals for this or that pattern of development or this or that disease. The eventual developmental outcome is affected by the specific experiences the individual may have from conception onwards. Maintaining good nutrition and obtaining pre-natal care is necessary. match to Institute of Medicine, 1990 development before and during pregnancy is important to defend against specific defects and diminish overall vulnerability. Mineral and Vitamins including iron, zinc, calcium and vitamin A have been proved to be native for the normal development of the fetus. Early, competent, pre-conceptual and prenatal care is also vital as they not only help birth defects but also reduces the rate of low- birth weight.Avoiding teratogens is vital to avoiding defects on the unbo rn infant. The American Academy of paediatrics recommends that parents read, sing, talk and play music for their baby inside the womb. It is believed that cognitive development starts inside the womb, and hearing music and parents voices helps develop a babys emotional state. In addition, many researchers believe that hearing a mothers and fathers voices regularly before birth helps babies learn who their parents are so that those voices can better soothe them after they are born. The Mayo Clinic has also published several studies showing that babies, who are read, contend music, sung or spoken to regularly have shown signs of being calmer babies, and may have a better emotional connection with their parents or caregivers.After birth environmental factors such as the food we eat, the air we breathe, the physical and social contexts we experience, our relationships and our continual ongoing interactions at work, at home and at play are necessary for a person to develop well. For ex ample while considering the type of parenting, permissive parents set few rules and rarely retaliate misbehavior. Their children will be less likely to adopt positive standards of behavior. Children embossed by authoritarian parents who resort to discipline, might develop low self-consciousness and are more socially withdrawn (Kaufman & Cicchetti, 1989).They tend to be more aggressive and are more likely to become juvenile delinquents (Bower, 1990). According to Baumrind, 1993 the best approach to child rearing is authoritative parenting. These parents are prompt and loving, yet insist their children behave appropriately. They encourage independence within light limits, show willingness to explain the reasons for the rules, and permit children to verbalize their disagreement with them. Their children are more likely to become socially competent, independent and responsible.ConclusionWhile some aspects of development may be strongly influenced by biology, environmental influence s may also play a role. For example, the timing of when the onset of puberty occurs is generally the results of heredity, but environmental factors such as nutrition can also have an effect. While the genetic instructions a child inherits from his parents may set out a road map for development, the environment can impact how these directions are expressed, shaped or event silenced. The complex interaction of nature and nurture does not just occur at certain(p) moments or at certain periods of time it is persistent and lifelong. Clearly, genetics have an enormous influence on how a child develops. However, it is important to guess that genetics are just one piece of the intricate fix that makes up a childs life. Environmental variables, including parenting, culture, education and social relationships also play a vital role.Berger, K. S. (1998).
