Test for linkage between the eumelanin dilution blue (B1), the extended black (E) allele at the E-locus and the linked pea comb (P) and eumelanin extension (M1) genes in the domestic fowl.

Abstract excerpt

1. A mating was made between a Blue Andalusian bantam male and a pea comb striped necked bantam female to produce a quadruple heterozygote of the linked pea comb (P) and eumelanin extension (Ml) genes and of the eunmelanin dilution blue (Bl) gene and the extended black (E) allele at the E-locus. 2. Two pea comb blue females so produced were mated to a single comb striped necked bantam male, thus providing a...
