That headline is a little vague.

Cats inherit a size-limiting gene from each parent, but the one from the father is ALWAYS shut down. Cats' size is limited by the gene they inherit from their mother. Female tigers have this growth-limiting gene. The issue is that the tiger growth-limiting gene does not send signals that get received in Ligers, so the gene doesn't work.
