Abstract

Goat color inheritance was evaluated based on color description of 218 kids and their parents (10 sires, 178 dams) from mixed crosses between several goat populations in an experiment on cashmere fiber production. Altogether 10 color patterns were observed. They were postulated to be caused by 10 alleles at the Agouti locus, with the allele for white or tan color being the top dominant allele, and the nine others codominant. The bottom recessive allele, for nonagouti color, was the 11th allele at this locus. The postulated alleles are white or tan (A(wt)), black mask (A(blm)), bezoar (A(bz)), badgerface (A(b)), grey (A(g)), lightbelly (A(lb)), swiss markings (A(sm)), lateral stripes (A(ls)), mahogany (A(mh)), red cheek (A(rc)), and nonagouti (Aa). Two types of eumelanin pigment were observed, black and light brown, the latter being dominant. Recessive brown was not observed.

摘要

在一项羊绒纤维生产实验中,基于对来自几个山羊群体杂交后代的218只羔羊及其父母(10只公羊、178只母羊)的颜色描述,对山羊颜色遗传进行了评估。总共观察到10种毛色模式。推测它们是由刺鼠基因座上的10个等位基因引起的,其中白色或棕褐色的等位基因为最显性等位基因,其他9个为共显性。该基因座上的第11个等位基因为非刺鼠色的最隐性等位基因。推测的等位基因分别为白色或棕褐色(A(wt))、黑色面罩(A(blm))、岩羊色(A(bz))、獾脸(A(b))、灰色(A(g))、浅色腹部(A(lb))、瑞士斑纹(A(sm))、侧条纹(A(ls))、桃花心木色(A(mh))、红脸颊(A(rc))和非刺鼠色(Aa)。观察到两种真黑素色素,黑色和浅棕色,后者为显性。未观察到隐性棕色。
