Dec 15th, 2016: Clones
Do these six horses look similar? They should, they're all clones of the same mare.

So far in the US, equine cloning has primarily been used in Arabians (whose registry states that the clone must accompany its original EVERYWHERE) and Quarter Horses--where there is considerable discord over the cloning of a horse named Smart Little Lena. One of the all-time great cutting horses, yes. But he carried (the original has passed away of old age) a recessive genetic disease known by the acronym HERDA. HERDA is a horrible, horrible thing...it affects the collagens that keep the skin working properly, with the result that an affected horse (which does require 2 copies of the gene) scars horribly from even the least scrape or tear. When HERDA horses are first saddled, any wrinkle in their skin becomes a tear; most do not live past the age of 4. If they do they're at high risk of literally having huge areas of their skin just...peel off. I see it over and over lurking on horse forums--"I don't have any ethical objection to breeding to a clone, but I wouldn't use one that carried HERDA!" I guess the moral is: horse people are okay with the concept of cloning but a lot of 'em wish it would only be used on horses that don't carry well-identified lethal disease recessives.
