A Bull Calf Has Been Genetically Optimized To Produce 75% Males

Using the genome-editing technology CRISPR, researchers can make targeted cuts to the genome or insert useful genes, called a gene knock-in, and they have done it with the cattle SRY gene, responsible for initiating male development, into a bovine embryo. ...
