The genetic basis of early-life morphological traits and their relation to alternative male reproductive tactics in Atlantic salmon.

Abstract excerpt

Although heritability estimates for traits potentially under natural selection are increasingly being reported, their estimation remains a challenge if we are to understand the patterns of adaptive phenotypic change in nature. Given the potentially important role of selection on the early life phenotype, and thereby on future life history events in many fish species, we conducted a common garden experiment, using...
