Genetics was my favourite part of biology class, and is one of the reasons that I sometimes wish that I’d continued studying science past high school. I still follow science news, though, and was intrigued by this article about the Quagga. There are only 23 hides left, and yet from these 100+ year old skins they were able to extract enough DNA to analyse it and plan a breeding program. Thank goodness that there are still enough Plains zebras around to make such a project feasible. I doubt a similar program would work with the big cats or the rhinos (there’s a subspecies of black rhino, I think it is, that is near extinction): the gene pool just isn’t varied enough.
