en.wikipedia.org/wiki/Dominance_(genetics)

If AA and aa individuals (homozygotes) show different forms of some trait ( phenotypes), and Aa individuals (heterozygotes) show the same phenotype as AA individuals, then allele A is said to dominate, be dominant to or show dominance to allele a, and a is said to be recessive to A. Dominance is not inherent to either an ...

Through the evaluation of many independent experiments performed on pea plants, Mendel found that individuals inherit two genes for each trait, one from each parent. In addition, if the alleles for these traits differ from one another, one of the alleles is expressed, while the other is not. Figure 10.1. For example, as indicated ...
