Gene editing to produce animal 'super dads'

Recommended Posts

Still Waters

Scientists have successfully created animal surrogate fathers that carry only the genes of donor animals -- nicknamed "super dads" -- in a step forward for gene editing with potential implications for global food production.

Researchers from universities in the United States and United Kingdom produced male pigs, goats, cows and mice whose sperm carry the genetic traits of another male individual.

That means when these "super dads" breed, the resulting offspring are expected to carry all the male donor's genes instead of the surrogate's.

"With this technology, we can get better dissemination of desirable traits and improve the efficiency of food production," said Jon Oatley, a biologist at Washington State University who led the research team, in a news release from the university on Monday.
