How can you use “underdominance” in a sentence? Here are some example sentences to help you improve your vocabulary:
In this report, we show that although population heterozygote advantage is compatible with allele-specific overdominance, it is also compatible with the opposite; i.e., population heterozygote advantage could arise in a population in which every heterozygote had a worse disease outcome than either of the corresponding homozygotes ("allele-specific underdominance").
We show that, depending on allele frequencies at the HLA locus of interest, population heterozygote advantage may occur when there is allele-specific overdominance, but may also occur under other conditions, including allele-specific underdominance.
It can also accommodate overdominance of the resistant alleles ( a > 1; b > d ; c > d ), in which each heterozygote does better than either corresponding homozygote, and underdominance, in which each heterozygote does worse than either corresponding homozygote ( a < 1; b < 1; c < d ). In this model, susceptibility and resistance are relative and simply refer respectively to lower and higher probabilities of favorable disease course, given infection.
Specifically, the conditions to observe population heterozygote advantage are broadest when allele-specific overdominance holds and become narrower as the underlying genetics becomes more "different" from overdominance of resistance (dominance -> additivity -> recessiveness -> underdominance).
