title: Hereditary congenital baldness: a sex-linked trait in the domestic fowl.
abstract: Congenital baldness in the domestic fowl is a genetic condition in which small irregular skin areas are devoid of down feathers (and later definitive feathers) over one or both eyes and/or the center of the head. In this study, the expression of congenital baldness was quite variable and ranged in size from a few follicles to areas as large as 10 mm2. The area over the right eye and the center of the head was more frequently involved than was the area over the left eye. This condition was inherited as sex-linked recessive. The symbol ba was assigned to the gene, and it was shown to be linked to the sal locus by 7.6 to 8.2 crossover units. An unusual feature was that 5% to 13% of heterozygous males exhibited the trait.
