WebIn population genetic terms, evolution is defined as a change in the frequency of specific gene in a population. Using the ABO blood system as an example, the frequency of the gene that codes for A blood protein, IA, is the number of copies of that gene divided by the total number of all A, B or O blood protein coding genes in the population. WebJan 3, 2024 · Sexual reproduction involves the alternation of diploid (two copies of each chromosome) and haploid (one copy of each chromosome) cell types. In a diploid cell, the two copies of a particular gene can be different, the the organisms is said to be heterozygous for that gene. Different alleles can (but do not necessarily do) encode …
