World’s Oldest Genome Sequenced From 700,000-Year-Old Horse DNA

Samples from a horse leg bone more than 700,000 years old have yielded the oldest full genome known to date.

The ancient horse genome also allowed the team to determine the evolutionary relationship between modern domestic horses and the endangered Przewalski’s horse, a native to the Mongolian steppes that represents the last living breed of wild horse.

The team found that Przewalski’s horses were an offshoot of the lineage that gave rise to domestic horses. The two groups diverged around 50,000 years ago.

Another breakthrough in colour genetics (or, if you prefer, “They’ve more or less dun it”)

5 05 2008

Ma préférée, originally uploaded by freddou_lutra.

Dun factor genetic testing is now available. Sort of. According to UC Davis, “The specific mutation that causes Dun has not yet been identified, and there is no direct test for the gene. VGL has identified DNA markers associated with Dun that can be used to determine if a horse has the Dun gene and how many copies.” They’re still doing research to pinpoint the exact genes, but this is still an exciting breakthrough. Also check out this article on primitive markings from Dun Central Station.

World’s first cloned horse has a foal (the old-fashioned way)

5 05 2008

Prometea, a cloned Haflinger mare, gave birth to Pegaso on March 17; full story here. Interesting that her creator, Professor Cesare Galli, has faced criminal and religious sanctions for his reproductive research. Anyone know what legal grounds Italian authorities would have for seizing a cloned bull?

Brindle filly

Stripes

I noticed this stripey girl at Heaven Can Wait equine rescue. Not much is known about her except that she’s a Standardbred cross, 1.5 years old and in need of some TLC. (“But Defrost, what’s a brindle horse?”)

Oh man, I am in LOVE

16 08 2007

with Fugly Horse of the Day:

This blog exists to object publicly to the breeding of fugly, often mixed breed horses which tend to have short, miserable lives and wind up in slaughterhouses. If you are not going to breed quality, don’t breed at all. It is not “cute” to have a cowhocked, knock kneed, fugly draft/QH/warmblood cross foal that you don’t do shit with and then dump for $150 at a killer auction as an unhandled two year old that runs people over. I see it ALL the time and I am SICK of it. If you do this, YOU SUCK. And that’s why I’m online bitching about you. Stop breeding the fugly, folks. There is no market for it. And if you don’t know what fugly is, read this blog and learn. My e-mail is resqtb@yahoo.com and I am usually way behind on e-mail, so don’t be offended if you do not get a response right away.

Another advocate of RESPONSIBLE breeding, hooray! Sometimes cruel but always on target. Go bookmark it NOW. (Found via Carinya Park)
