Oysters show heterozygosity correlates with growth but selection’s focus stays unclear.

Evidence

Electrophoretic studies of the American oyster, Crassostrea virginica, provide some of the strongest evidence for a relationship between heterozygosity and a fitness-related character within a natural population; at the same time, they provide a good example of the difficulty in determining the actual foci of natural selection. — S.
