In the absence of mutation or heterozygote advantage, any allele must eventually be lost completely from the population or fixed (permanently …
Web16 jun. 2024 · Alleles, by definition, are gene variants. The concept of dominance was first introduced by G.J. Mendel in 1860. Although he didn’t use the terms gene, allele, phenotype, etc ., he introduced the principles that later founded the laws of Mendelian Inheritance. One of these laws is the Law of Dominance.
