The Horse Genome

The genome of the domestic horse has been mapped by a team of scientists.

The team surveyed the extent of genetic variation both within and across breeds to create a catalogue of more than one million single-letter genetic differences in these breeds.

This is slightly larger than the genome of the domestic dog, and smaller than both the human and cow genomes.

So far, scientists have also sequenced the genomes of the platypus, mouse, rat, chimpanzee, rhesus macaque and, of course, human.

I'd be interested in the genome of the dolphin and whale....
