Two rapidly evolving genes offer Cornell geneticists clues to why hybrids are sterile or do not survive
01-Dec-2006 -
While hybrids may offer interesting and beneficial traits, they are usually sterile or unable to survive. For example, a mule, the result of the mating of a horse and a donkey, is sterile. Now, Cornell researchers have made the first identification of a pair of genes in any species that are ...
