Abstract
Starch gel electrophoresis of the plasma of pigeons, ring neck doves, dwarf turtle doves, and mourning doves revealed constant distinct bands in the plasma-albumin different for each species. In hybrids among some of these species, the albumin showed both parental components as double bands. The hybrids from dwarf turtle doves x ring neck doves were fertile. There were 24 progeny from 1 family in the 1st backcross plus 335 offspring from 58 second and later backcrosses and matings inter se of the backcross hybrids. The ratios conformed to expectations on the assumption of a monohybrid, co-dominant, autosomal gene pair. No linkage of the albumin types was noted with 6 other character pairs. 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.
