^*Embryonic tissues were recovered from sectioned decidua (see text and Materials and Methods). 

^†Only those embryos that showed trophoblast outgrowth and propagation of the ICM cells in the following culture were genotyped. Of 59 blastocysts examined, 6 did not show outgrowth, and could not be genotyped, accordingly.
