If the individual was really a heterozygote, approximately fifty per cent.

In the above equations, s is a selection coeﬃcient and h is a dominance parameter which controls the contribution of the master sequence to the ﬁtness of the heterozygote.
Nonlinear deterministic equations in biological evolution
The dominance is absent when h = 1/2 as the heterozygote ﬁtness W (0, σ) = 1 + s is the average of the master ﬁtness and the mutant ﬁtness.

He or she can choose the same allele twice (homozygote) or different alleles (heterozygote).

A is the heterozygote, AA is the risk homozygote) is known.

Thus, the imperfect LD will change certain models, such as the dominant or the recessive models, so that the heterozygote penetrance will have an intermediate value between those for the homozygotes.
