Example sentences for: overdominance

How can you use “overdominance” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In this situation, population heterozygote advantage does not require overdominance, but merely allele effects that are more than additive (partial dominance).

  • The intuition behind our result that population heterozygote advantage need not reflect allele-specific overdominance can be seen in two simple examples.

  • 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.

  • 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).
