Geneticist use CRISPR to change animal’s sex
15 January 2018 | Written by La redazione
Australian geneticist Alison Van Eenennaam of the University of California, after a year of trying, managed to used the gene-editing tool CRISPR to add a gene called SRY to some bovine skin cells. And SRY is no ordinary bit of DNA. All on its own, the presence of SRY can make a female turn out to be essentially male—with bigger muscles, a penis, and testicles (although unable to make sperm). Gene-editing technology has big potential in farm animals. It has been used to create pigs immune to viruses and sheep whose wool grows longer.
