Which breeding method involves transferring embryos from a donor to recipient females?

Embryo transfer is the process of moving developing embryos from a donor female into recipient females so they can carry the pregnancies to term. This method lets multiple offspring come from a single high-quality dam by collecting her embryos and delivering them into synchronized recipient females. Artificial insemination, by contrast, deposits semen to fertilize eggs inside the dam, not transferring embryos. In vitro fertilization involves fertilizing eggs outside the body and then transferring the resulting embryos to recipients, but the action described—transferring embryos from a donor to recipients—matches the embryo transfer method itself. Selective breeding is about choosing which animals mate to improve traits, without moving embryos between animals.
