Figure 4

Electrophoretogram showing normal XY male sex chromosome constitution. Both the X- and Y- specific products of the AMXY (X-Y amelogenin gene) are present with a normal ratio of 1 : 1. The XY male sex chromosome constitution is confirmed by the occurrence of the SRY product. In this example, the presence of two sex chromosomes is also further confirmed by the normal heterozygous pattern of both pseudoautosomal markers X22.
