Wing-size heritability in a natural population of Drosophila subobscura
Article Abstract:
Heritability of wing size has been studied in two consecutive years in a natural population of the European species Drosophila subobscura. The study shows that it is important to determine the environments in which the parents developed in nature before considering heritability values. In the first sample in the laboratory environment heritability was about 15%. The lower bound in nature was about 0.1%. For the second year, heritability in the lab was about 90% and that in nature about 15%.

Inheritance mode of Drosophila simulans female mating propensity with D. melanogaster males
Article Abstract:
The female mating propensity of Drosophila stimulans from different geographic origins with D. melanogaster males was investigated to determine the genetic factors involved in their sexual isolation. Findings revealed the presence of genetic variability in D. simulans for this trait. Female discrimination was found to be dominant against high female interspecific mating, which differed from that detected in other Drosophila species.
