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).
That is, even when allele-specific overdominance holds, it is possible that heterozygotes on average will do worse than homozygotes, so population heterozygote advantage will not be observed.
The intuition behind our result that population heterozygote advantage need not reflect allele-specific overdominance can be seen in two simple examples.
Our results do not deny that allele-specific overdominance at HLA exists in human populations with respect to infectious disease resistance, but simply raise doubts about the reliability of the major evidence that has been adduced in support of this phenomenon.
A study in mice of resistance to Toxoplasma gondii showed that F 1 offspring of two genetically divergent parent strains were more resistant than either parent strain, but there seems to be no demonstration that heterozygosity at an MHC locus is responsible [ 18 ] , while another reference [ 19 ] that has been cited [ 10 ] as showing overdominance at MHC in the same host-pathogen system does not appear to address the question directly.
