== In humans == The best-known example of disassortative mating in humans is preference for genes in the [[major histocompatibility complex]] (MHC) region on chromosome 6. Individuals feel more attracted to odors of individuals who are genetically different in this region.<ref>{{cite journal |last1=Wedekind |first1=Claus |title=MHC-dependent mate preferences in humans |journal=Proceedings of the Royal Society of London. Series B: Biological Sciences |year=1995 |volume=260 |issue=1359 |pages=245β249 |doi=10.1098/rspb.1995.0087 |pmid=7630893 |s2cid=34971350 |url=https://royalsocietypublishing.org/doi/abs/10.1098/rspb.1995.0087|url-access=subscription }}</ref> This promotes MHC heterozygosity in the children, making them less vulnerable to pathogens.
