Abstract
Four of 24 bovine embryos (days 5-7) subjected to chromosome analysis had haploid cells in metaphase. Two were clearly n/2n. The origin of the haploid cells was determined to be male in 2 embryos, owing to the presence of a Y chromosome or a male marker chromosome suggesting spermatozoa in division.This publication has 7 references indexed in Scilit:
