In contrast, estimates from
multilocus genetic data are consistent with a much higher original population size (78,000 — 116,000 individuals)[5].
Here, we used parentage analysis with
multilocus microsatellite markers to measure how varying levels of
genetic introgression with non-native rainbow trout (Oncorhynchus mykiss) affect reproductive success (number of offspring per adult) of native westslope cutthroat trout (Oncorhynchus clarkii lewisi) in the wild.
