Abstract:
The heritability of larval size is
estimated in Mytilus chilensis, based on a nested design, involving
95 full-sib and 19 half-sib families (19 males each mated to 5 separated
females) grown under controlled laboratory conditions. The half-sib
heritability estimates at 10, 25 and 40 days for larval and spat shell
height ranged between 0.38±0.33 and 0.84±0.45, suggesting that selection
for shell size would be effective.
