指相同基因座上的基因发生不同突变所引起的相同或者相似的表型。 异质性：是指一对等位基因分别控制一对相对性状遗传
不同基因型决定相同表型的现象。参见等位基因异质性、临床异质性和基因座异质性。
Genetic lethal --- A mutant allele or genetically determined trait that leads to failure to reproduce, although not necessarily to death prior to reproduction.
通过分析肿瘤细胞的密度及等位基因突变的几率来确定肿瘤异质性和等位基因特异性突变的不平衡性。
Tumor cellularity and mutant allele frequency were analyzed to identify tumor heterogeneity and mutant allele-specific imbalance.
等位基因突变几率预测肿瘤异质性方面低于预期，但等位基因突变几率预测等位基因特异性突变不平衡性方面则高于预期。
Lower than expected mutant allele frequency indicated tumor heterogeneity, while higher than expected mutant allele frequency indicated mutant allele-specific imbalance.
