Almost 100 years have passed since Heape (1891) reported the transfer of two-cell embryos from an Angora rabbit to the oviducts of a pregnant Belgian hare. This experiment showed that the reproductive tract of the recipient had no effect on the genetic composition of the fetus, because ...

Although the first mammalian embryo transfers were done more than 100 years ago, commercial bovine embryo transfer came into being in the early 1970s with the importation of European breeds of cattle into North America. Since that time commercial bovine embryo transfer has grown throughout the worl...

This is particularly true because early-stage embryos of these animals (e.g., cattle) often are not considered to be good candidates for transfer to recipient females, since acceptable pregnancy rates are not usually achieved until embryos reach the morula or blastocyst stage of development. If ...
This procedure obviously leads to a shortened generation interval resulting therefore in higher rates of genetic improvement. However, application of the OPU-IVP technique is also accompanied by some disadvantages that still need to be solved. In general, the pregnancy rate after embryo transfer is ...
Understanding how each gene in our genome contributes to our individual phenotypes during embryogenesis is a fundamental goal of developmental genetics. Genetic screens in multicellular animals have enabled the dissection of diverse developmental processes, illuminating the functions of thousands of genes. Al...
