Is the heritability for courtship and mating speed in Drosophila (fruit fly) low?
Article Abstract:
Repeated measurements have been made of time-to-courtship and mating speed in the same individuals among Drosophila melanogaster, fruit flies. Heritabilities were intermediate and significant when behavior of each individual was averaged for several events. Estimates for mating behaviors that relate to the fitness of organisms are much higher than was found through single-event observations. In the past empirical studies have indicated that heritable variation for courtship behavior in Drosophila is usually not measurable. Mating speed, on the other hand, was found to have low heritability.

A study of fluctuating asymmetry in hybrids of dwarf and normal lake whitefish ecotypes (Coregonus clupeaformis) from different glacial races
Article Abstract:
Results show variable degree of asymmetry in several traits in whitefish ecotypes studied but no significant fluctuating asymmetry in different crosses. Data further indicate that there is no experimental evidence to relate genetic stress of embryonic stage to those at late developmental stage.
