Derived trait vs ancestral trait
WebNo matter whether fixation of the derived allele occurs as a result of selection or as a result of genetic drift, this fixation corresponds to extinction of the ancestral allele. WebAncestral characteristics are the ones that are shared by (in this example) salamanders, pigeons, AND their most recent common ancestor. That’s why they’re considered ancestral. Derived characteristics are the ones that evolved after they diverge on the phylogenetic tree. elliebrolo • 3 yr. ago AND their most recent common ancestor
