Solution
Soyabean trypsin inhibitor retard separation of of vitelline layer from surface of egg and formation of the fertilization membrane .Attached portion of vitelline layer decreases in number and by approximately 15mm post insemination cortical projection are spare.SBTI treated zygote show corresponding decline in both incidence of Refertilization upon reinsemination.
