Abstract

The autosomal gene for naked neck in domestic fowl has been shown to be incompletely dominant. Heterozygotes characteristically have an isolated tuft of feathers on the ventral side of the neck above the crop. Homozygotes lack this tuft completely, or it may be reduced to a very few pinfeathers or small feathers.

摘要

家禽中裸颈的常染色体基因已被证明是不完全显性的。杂合子的特征是在嗉囊上方颈部腹侧有一丛孤立的羽毛。纯合子则完全没有这丛羽毛，或者它可能减少到只有很少的绒羽或小羽毛。
