Abstract

The inheritance of leg-feathering in crosses of the Black Langshan (feathered) with the White Plymouth Rock and Buff Orpington breeds (non-feathered) has been found to be dependent upon two dominant duplicate factors (S1 and S2). This relationship has been verified from data secured from F2 and backcross generations. Of five F1 males used in these studies three proved to be heterozygous for both factors S1 and S2 and two for but one of these factors, while six F1 females proved to be heterozygous for both factors and ten for but one factor. These data indicate, therefore, that the Black Langshan is often heterozygous for at least one pair of these factors.
