Supergene

A supergene is a chromosomal region encompassing multiple neighboring genes that are inherited together because of close genetic linkage, i.e. much less recombination than would normally be expected.[1] This mode of inheritance can be due to genomic rearrangements between supergene variants.

A supergene region can contain few, functionally related genes that clearly contribute to a shared phenotype.[2]
