Genotypes example biology
WebIn overdominance, both alleles are maintained in the population because the heterozygotes have a selective advantage over both homozygous genotypes. This can lead to genetic diversity being maintained in the population. In contrast, directional selection can lead to the loss of genetic diversity, as the distribution of the trait shifts towards ... WebFor example, feather colour in hens may be white, black or speckled (it has both white feathers and black feathers). The alleles can be shown as W for white and B for black. There are three ...

WebFor example, the phenotypes that Mendel observed in his crosses between pea plants with differing traits are connected to the diploid genotypes of the plants in the P, F 1, and F 2 generations. We will use a second trait that Mendel investigated, seed color, as an example. Seed color is governed by a single gene with two alleles.
WebApr 24, 2024 · The genetic makeup of an organism is called its genotype and its observable traits are its phenotype. In other words, what a person looks like is the result of his or her DNA.
