The current percentage of D ( dominant ) alleles in the population varies because the population depends on the Genotype of the organism. the genes of the organism is been affected by factors such as mutation and this will change the Genotype of the organism leading to the varying number and percentage of D ( dominant ) alleles in the population of organisms.
The D alleles dominate the variants of Genes found on a chromosome or other copy of the chromosome.
The number of the dorminat alleles varies with the genotyoe. In addition, the factors as mutation also contribute to the mutation of the genes. The mutation in the DNA causes a different set of instruction in the DNA. This then affects the gene expression in an organism.
