Wing-size heritability in a natural population of Drosophila subobscura.

Abstract excerpt

Heritability of wing size was determined in a natural population of Drosophila subobscura for two consecutive year samples. In the 1988 sample, heritability in the laboratory environment was around 15%, whereas the lower bound in nature was around 0.1%. On the other hand, in the 1989 sample, heritability in the laboratory was around 90% and in nature around 15%. Differences between the two years could be caused...
