Scientists create gene-edited animals as ‘surrogate sires’ to boost food production – The Tribune

LONDON: Scientists have created gene-edited pigs, goats and cattle to produce sperm with traits such as disease resistance and higher meat quality in what they say is a step towards genetically enhancing livestock to improve food production.
 The animals, created for the first time by researchers in the United States and Britain using a gene-editing tool called CRISPR-Cas9, could be used as “surrogate sires”, essentially sterile blank slates that could then be transplanted with stem cells that …
