Correlations among size-related traits affected by chromosome inversions in Drosophila buzzatii: The comparison within and across environments
Genetic variation in correlations among size-related traits of head, thorax, and wines was examined in Drosophila buzzatii by comparing the pattern of the Phenotypic Correlation Matrix (R(p)) between inversion karyotypes of the second chromosome. No similarity in R(p) was observed between some karyo...

Genetic variation in correlations among size-related traits of head, thorax, and wines was examined in Drosophila buzzatii by comparing the pattern of the Phenotypic Correlation Matrix (R(p)) between inversion karyotypes of the second chromosome. No similarity in R(p) was observed between some karyotypes in a natural population. The pattern of R(p) in wild-reared heterokaryotypes, but not in homokaryotypes, was similar to the whole population represented by laboratory reared flies. While phenotypic correlations in wild-reared flies were found to be larger than in laboratory-reared flies, similarity in the pattern of R(p) was very high for one homokaryotype reared in both environments: the relatively homogeneous lab environment and the more variable field environment. While no such a similarity across environments was detected between different karyotypes, the pattern of R(p) was similar for a same homokaryotype in different populations. Thus, the lack of karyotypic similarity in R(p) is, at least partially, genetic.
