hemizygous gene

A gene present in only one copy in a diploid organism for example, X-linked genes in a male mammal.

heterozygous gene pair

A gene pair having different alleles in the two chromosome sets of the diploid individual for example, Aa or, A1A2.

histocompatibility gene

A gene encoding an histocompatibility antigen.

homeotic mutations (genes)

Mutations (defining genes) with a phenotype in which a given cell develops along a pathway normally followed by a different cell type. Mutations that can change the fate of an imaginal disk in insect development.
