Genetics and Child Development Essay
Genetics play a lively role in our development and that of our clawren. Our genic make-up, or traits, directly affects our pincerrens development, from the moment of conception and the beginnings of a new person, throughout his or her life. The childs developmental fate is all in the deoxyribonucleic acid, (desoxyribonucleic acid). Deoxyribonucleic acid, is fashi unitaryd in the shape of a double helix a twisted fall apart of genetic code, which along with various proteins, which ar essential to aid the DNA in proper cell division, are found in chromosomes. These are the microscopic structures that contain all an individuals genetic culture which are found in every cell of the human luggage compartment except red blood cells, which have no nuclei (TGC, 2013). Half our chromosomes (23) advance from our father, and the other half from our mother, for a total of 46.Together, this set of 23 pairs of chromosomes is liable for giving us our hair people of colour, eye color, heig ht, the shape of our earlobes, our facial features, our shape, and the color of our skin our genotype, or transmissible traits from both parents genes (Mossler, 2011). pincer development is restricted on genetics and the compatibility and health of the combined parental sets of chromosomes (GSLC, n.d). Things can go wrong, and parts of essential chromosomes whitethorn be deformed, rearranged, ab conventionalism or wanting this can wreak havoc on the well-being of the developing fetus, resulting in deformities, mental retardation, and birth defects (GTC, 2013, para.1, sub sect. 2). Risk factors for a higher incidence of these chromosomal ab publicities include maternal age, and sometimes paternal age, and/or they whitethorn be due to a glitch in meiosis the butt on where gametes or sex cells are formed the egg (ovum), and the sperm, each containing 23 chromosomes (GSLC, n.d).Genetic counselors talk to couples before conception or during their pregnancy, regarding any worries th ey may have with their combined family genetic history. The counselor is consulted to assess the outcomes of possible genetic disorders such as Tay-Sachs, Cystic Fibrosis, squander syndrome, and many others. Fetal discussion may be a distinct possibility for some inherited disorders with which a genetic counselor may assist couples. waste syndrome is one of the most super C chromosome ab formulaities, which is recognized by a duplicate replicate of chromosome 21. Babies with carry out syndrome have flat features, including extra skin behind their necks, short, short hands, and recessed chins. Their eyes look as if they were born of Mongolian heritage, and Down syndrome was formerly known as Mongolism in the pre-1965 era, due to this select feature, even though it has nothing whatsoever to do with this particular syndrome.The boundary Mongolism was dropped in 1965 by the World Health Organization (WHO), (Lowe, 1949). enate age is relevant when it comes to an elevated risk of Down syndrome according to a study, 1/350 normal live births born to mothers age 35 resulted in Down syndrome whereas, one Down syndrome birth in 85 normal live births occurred when the maternal age was 41. Mothers over 45 years of age, had a 1/25 chance of giving live birth to a baby with Down syndrome (Hook, 1983). Oddly enough, 80 percent of Down syndrome occurs at a maternal age of less than 35 (TGC, 2013, para.1, sub sect. 2). sister development of the child with Down syndrome is held on a parallel with normal children however, the child with Down syndrome may achieve with less competence than that of his normal classroom counterpart. Evidence reveals that children with Down syndrome benefit from integration and interaction with others in a normal school environment. In particular, they show significant gains in spoken language, reading, writing and arithmetic.This enhances their ability at a later stop to successfully interact with adults and become reproductive members of society (Buckley & Sachs, 2001). When I had my youngest child at almost 42 years-old, I had amniocentesis to test for Down syndrome and other abnormalities, as I was an older mother. My obstetrician believed I may be carrying twins however, he came to the conclusion that my single baby intent his twin in utero, which today is quite commonplace. Cystic Fibrosis is the most common genetic disease in Caucasians. The incidence is 1/300, and 4 5 percent of Americans are carriers.Chromosome 7 is the one affected here, whereby it is caused by a change in a single nucleotide (a phosphoric ester of a nucleoside the basic structural unit of nucleic acids, DNA or ribonucleic acid (RNA). This disease affects the respiratory tract, in that it becomes clogged by mucus, which increases the incidence of pulmonary infection. Additionally, secretions bar the pancreas, which leads to dietary problems (GSLC, n.d). Cystic Fibrosis or 55 Roses as it is commonly called by children suffering from the disease, affects child development by posing cognitive, emotional and behavioral challenges. To conclude, in writing this paper I have developed a better understanding regarding the world of genetics and chromosomal diseases and their effect on child development.Children and their individual development through the various stages of these chromosomal diseases and disorders stage many challenges for them to overcome, and are more often than not, life-changing events for their families. Life expectancy for CF sufferers is not longevity however, the quality of their limited lifestyles should be paramount in spite of appearance their familys goals to make their childs life on background as pleasant a time as possible. Down syndrome, however, although externally obvious to the perfect stranger, is nevertheless one of the milder forms of chromosomal diseases that can be worked through, albeit a challenge, to transform the sufferer into a fully functioning productive member of society .ReferencesBuckley S.J., Sacks B., (2001) An overview of the development of children with Down syndrome (5-11 years).
