We demonstrate a new method, microarray-assisted bulk segregant analysis, for mapping traits in yeast by genotyping pooled segregants. We apply a probabilistic model to the progeny of a single cross and as little as two microarray hybridizations to reliably map an auxotrophic marker, a Mendelian trait, and a major-effect quantitative trait locus.
我们展示了一种新方法——微阵列辅助混合分离群体分析法,用于通过对混合分离群体进行基因分型来定位酵母中的性状。我们将概率模型应用于单个杂交的后代,并只需进行两次微阵列杂交,就能可靠地定位一个营养缺陷型标记、一个孟德尔性状和一个主效数量性状位点。
