A Males have smaller vocal cords and are less likely to make sounds. In one notable experiment, they followed a box placed on a model train in circles around the track. Neither chromosome is able to express genes from this region, leading to this disorder.

A small number of genes in mammals ~100 of them at a recent count and in have been found to be imprinted. Studying imprinting may help researchers understand how other genes make it through reprogramming without losing their epigenetic tags.

If the maternal copy of the gene mistakenly gets imprinted during development, then this copy is off, too. B genes enhance survival of copies of themselves by directing organisms to assist others who share those genes. The preference for some similarity presumably ensures that they attempt to mate with members of their own species.
