Fig. 5From: Characterization of the endogenous retrovirus insertion in CYP19A1 associated with henny feathering in chickenA portion of the backcross population pedigree. Animal IDs are indicated with italic numbers. Open glyphs indicate that the individual does not carry the Hf_ERV insertion, while half shaded indicates heterozygosity. ID 64 is a Hamburg wild-type male (hf+/hf+). He was used to generate both F1 and backcross progeny. The Hf genotype of females cannot be inferred by their phenotype because henny feathering is a male-limited trait. But their genotype can be inferred based on pedigree data. Therefore, female 544 and 81 are Hf/hf+ and all other females should be hf+/hf+Back to article page
