Eco-evolutionary model showing that heterozygote advantage can explain the extraordinary diversity of immune genes!

Our new paper (out in #eLife: doi.org/10.7554/eLif...) identifies the conditions under which heterozygote advantage can drive the evolution of such diversity, found in e.g. #MHC genes
Heterozygote advantage can explain the extraordinary diversity of immune genes
An eco-evolutionary model shows that heterozygote advantage can maintain over 100 major histocompatibility complex alleles, providing a potent explanation for extraordinary immune gene diversity and c...
