Abstract
SummaryStarch gel electrophoresis of the plasma of pigeons, ring neck doves, dwarf turtle doves, and mourning doves reveals constant distinct bands in the plasma albumin different for each species. In hybrids among some of these species, the albumin shows both parental components as double bands. The hybrids from dwarf turtle doves X ring neck doves are fertile. There were 24 progeny from one family in the first backcross plus 335 offispring from 58 second and later back-crosses and matings inter se of the back-cross hybrids. The ratios conformed to expectations on the assumption of a monohy-brid, co-dominant, autosomal gene pair. No linkage of the albumin types with the other characters was noted. A blurring of the non-albumin components of the plasma was noted in certain adult females of 4 species, a probable association with egg production.
