Heterozygozity maintenance for the lethals in populations reproducing by intratetrad mating
Maintanance of lethals in the gene pool is analyzed for a population reproducing by intratetrad mating (fusion of the spores formed by one meiotic division). It is shown that heterozygotes for the lethal are maintained stable in the population if they have advantage in reproduction rate compared with homozygotes carrying the normal allele (the effect of overdominance). The dependence of this advantage on the distance from the respective gene to the centromere is evaluated.
