Four foals were successfully born as the result of the transfer of genotyped and cryopreserved embryos. Researchers report that this is a first in Europe. The goal of this work is to better understand embryonic development, control livestock reproduction, and maintain breed genetic diversity. Furthermore, it is advantageous for the horse industry to be able to determine the traits of a future foal.
Genotyping allows scientists to choose the embryos they want to use based on different criteria: sex, like in this experiment, the absence of known genetic disorders, or, perhaps in the future, other traits that are tied to behavior, such as emotivity or sociability.
