I added it to the list on our Instructors' Blog, stated as follows:Students should be able to define dominance as a particular relationship between the effects of two alleles; dominance is said to exist when the phenotype of the heterozygote is the same as that of a homozygote for one of the alleles the 'dominant' one.

Other common autosomal recessive diseases such as sickle cell anemia have been found to protect carriers from other diseases, a concept known as heterozygote advantage.

This is where the heterozygote has a higher fitness than either homozygote.

He constructed a model with populations subdivided into numerous, semi-isolated subpopulations, or demes, in which spontaneous chromosome rearrangements with heterozygote disadvantage occur.

But if two dominant, or two recessive, alleles occur together in a heterozygote, interesting things can happen.
