Abstract
Divergence over time in flocks selected for clean fleece weight and for fecundity is measured by gene frequency changes at the R-r-i blood group, haemoglobin, and transferrin loci. No unequivocal effect of selection is demonstrable. Problems of interpretation even in flocks of known history are discussed.
摘要
通过R-r-i血型、血红蛋白和转铁蛋白位点的基因频率变化来测定选择了净毛量和繁殖力的羊群随时间的分化情况。未证实选择有明确的效果。文中还讨论了即使在已知历史的羊群中进行解读时存在的问题。
