| Popis: | Winging It Genes that explain phenotypic variation between species have only been identified within a handful of model organisms, which limits the scope and understanding of the genetics of phenotypic diversification. On investigating the phenotypic diversity in wing size among wasps of the genus Nasonia , Loehlin and Werren (p. 943 ) have identified the genetic basis of a morphological difference between two closely related species and showed how changes in regulatory elements have evolved to change expression of a single gene, unpaired-like ( upd-like ), a functionally conserved signaling gene. Overall, it appeared that significant morphological change was achieved through a series of relatively rapid, but small-scale changes. |
