| 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. |
