OA show ('918'); New Zealand official researchers concluded on July 2nd that a gene that can produce twin sheep will help solve human infertility This is the first time that genes have been found to directly affect the ability of the ovaries to hatch, rather than through the pituitary gland In 1968, when a New Zealand ewe named a281 was about to be sent to the slaughterhouse, its owner discovered its unusual reproductive ability In the fourteenth year of this sheep's birth, there were forty lambs, and many of her offspring were also fruitful Scientists have studied the gene of a281 ewe for a long time, and gradually solved the mystery of ovary It turns out that the mutation of GDF9B gene in X chromosome of this sheep increases the probability of multiple births Because GDF9B gene also exists in human body, this discovery is of great reference value for the future cure of infertility in medical field BYV (author:)
