Evidence for recombination and transgressive segregation of quantitative traits analysed in 18 members of the nasuta-albomicans complex of Drosophila. Correlation of Euclidean distance dissimilarity (Table 8) is computed to the traits assessed separately in males (7 traits), females (8 traits) and both males and females together (5 traits). Based on these values, the members are classified into three ranges, namely parental range, higher range and lower range. Many of these newly evolved Cytoraces are more fit in the laboratory than their parental species and exhibit phenotypes that are extreme relative to either parent. The generation of extreme phenotypes through recombination in segregating hybrids is referred to as transgressive segregation.
