Heterozygote advantage is the superior fitness often seen in hybrids, the cross between two dissimilar parents. A heterozygote is an organism with two different alleles, one donated from each parent. Fitness means the ability to survive and have...

A heterozygote is a diploid ( nucleus that contains two sets of chromosomes) organism with two different alleles (alternate form of a gene) at the corresponding loci. Sometimes the heterozygote is not phenotypically distinguishable because of the...

A heterozygote advantage (heterozygous advantage or overdominance) describes the case in which the heterozygote genotype has a higher relative fitness than either the homozygote dominant or homozygote recessive genotype. This selection favoring the...
