0 a person, animal, or organism that has two different forms of a gene (= part of a cell containing DNA information) that controls a particular characteristic, one inherited from each parent, and is therefore able to pass on either form: --
Heterozygotes have no manifestations of disease.
The heterozygote deficiencies were even higher in the other two species.
Estimating the effective number of breeders from heterozygote excess in progeny.
On the potential for estimating the effective number of breeders from heterozygote-excess in progeny.
This might be expected when haploids are compared with heterozygotes, but not necessarily expected when haploids are compared with homozygous mutant diploids.
The most important problem seems to be how the heterozygote of mutant alleles belonging to the same locus produced wild-type progeny.
This deviation was always towards a deficit of heterozygotes.
Polymorphism from environmental heterogeneity : models are only robust if the heterozygote is close in fitness to the favoured homozygote in each environment.
Populations reach a quasi-equilibrium, with mean fitness and heterozygote and homozygote number fluctuating around deterministic equilibrium levels.
