Embryo transfer is a type of biotechnology. It is used in the breeding of cattle, sheep, and goats. It allows an embryo to be transferred from the natural mother to a different female. This allows the natural mother to produce many more offspring than she otherwise could. What is the most likely reason that a particular female would be selected to be the natural mother that produces many embryos to be transferred to other females?
