Document Summary
Tries to specify the particular gene or genes involved and the precise functions of these genes. Each cell consists of 46 chromosomes (23 pairs) with thousands of genes per chromosome. Chromosome are out genetic material and one of each pair comes from a person"s mother and father. An allele is any one of several dna codings that occupy the same position or location ona chromosome. A persons genotype is his or her set of alleles. Genetic polymorphism: the variability that occurs among members of the species. It involves differences in the dna sequence that can manifest in very different forms among members in the same habitat. Entails mutations in a chromosome that can be induced or naturally occurring. For many years genetic discoveries involving humans have primarily been the product of extensive lines of research conducted initially with animals. Discoveries are made in animal research, and then, where feasible, the generalisability and applicability to humans has been evaluated.
