A striking feature of the allelic patterns detected by these probes was that cells with the same AH had identical Y, X and V alleles(i. e, the alleles were haplotypic).

这些等位基因的一个显著特点是：相同的AH具有相同的Y、X、V等位基因型（即呈单体型性质）。

They identified the donor cells by the presence of the Y chromosome that is only found in males.
