Gene Editing To Produce ‘Super Dad’ Livestock
Scientists have produced gene-edited animals they say could serve as “super dads” or “surrogate sires.” The BBC reports: The pigs, goats, cattle and mice make sperm carrying the genetic material of donor animals. The researchers used a hi-tech gene editing tool to knock out a male fertility gene in animal embryos. The animals were born sterile, but began producing sperm after…
Cloned testicles let goats father the offspring of another male
Biologists have created pigs, goats and mice whose testicles produce the sperm of a different male and which breeders could use to pass on desirable traits to many more offspring than normally possible Source: https://www.newscientist.com/article/2254419-cloned-testicles-let-goats-father-the-offspring-of-another-male/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
