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）。

When the two alleles are not identical, they are said to be heterozygous.

当两个等位基因不同时，称之为杂合性的。

When the two alleles are not identical, they are heterozygous.

杂合性：在一个基因位点上具有两个不同的等位基因。

Only identical twins share genetic profiles on all 20 alleles, so if you get a perfect match between the DNA you find at the scene and the DNA database profile, you have very strong evidence that the person in the database committed the crime.
