Heterozygosity and extra-pair paternity: biased tests result from the use of shared markers.

Molecular ecology - 1 May 2009

Wetzel Daniel P, Westneat David F

Abstract excerpt

Recent studies of extra-pair paternity have found support for the idea that heterozygous males have an advantage in siring offspring. Most studies use DNA microsatellite loci to determine paternity and then use the same loci to estimate individual heterozygosity. However, because the likelihood of detecting extra-pair offspring depends on the combinations of parental alleles, it is possible that biases arise from...
