Dbuz\In(2)z3 appears to increase female longevity.
The biometrical effect of inversions on body size is due to genetic differences between rearrangements and not to the historical relationship between the populations studied.
Genetic variation in correlations among size-related traits of head, thorax and wings are examined in D.buzzatii by comparing the pattern of the Phenotypic Correlation Matrix between inversion karyotypes of the second chromosomes. Results indicate chromosome inversions are factors affecting genetic correlations among traits known to be phenotypically correlated with adult fitness components.
Rearrangements are correlated with a large thorax size.
