Were Old McDonald in the genome sequencing business, he would be among the researchers who have announced decoding the complete genetic blueprints of the horse, pig and cucumber.

Knowing the details of these three genomes provides scientists with new information about the genetic makeup of economically useful animals and plants, but also helps answer some basic questions about biology and evolution.

A horse named Twilight, who lives at Cornell University, gave her DNA to the horse genome ...
