Trisomy 13: Not Always Genetics
Understanding the way our body is formed starting from the chromosomes to organ systems allows nurses to recognize genetic abnormalities. Comprehension of how these abnormalities change a person’s outward appearance and their bodily functions is expected of nurses. The aim of this paper is to explain how genetics and knowledge of genetics play a role in community nursing, and nursing in general. Genetics is the study of genes, genetic variation, and heredity of living organisms. Genes are the sets of chromosomes combined from the mother and father formed into the new set for the offspring. Sets of alleles forming the traits given to an offspring are called either genotypes, or when observable outwardly on the progeny they are called its phenotype. Traits are heterozygous as a gene with one allele is dominant, as its qualities dominate the phenotype of the organism, and the other allele is recessive. Recessive alleles qualities recede and are not observed over the dominant allele. Some alleles do not have complete dominance and instead have incomplete dominance by expressing an intermediate phenotype, or codominance by expressing both alleles at once. Combinations of traits and genes make up the different faces and characteristics seen in our world and communities. One person even if related, unless from identical chromosomes, will not ever look the same as another human being (Tortora & Derrickson, 2008).
