Sexually dimorphic gene expression responses of bovine embryos to the maternal microenvironment

ABSTRACT: This study investigated the sexual dimorphic gene expression patterns of day 13 embryos developed in Holsteins Frisian cows and heifers. Accordingly, embryos developed in the cows exhibited sexually dimorphic expression of genes associated with steroid biosynthesis and metabolism as well as genes associated with the formation of the primary germ layer whereas those developed in heifers sexually dimorphic expression of genes involved in developmental processes, gonadal development or female sex differentiation, and transmembrane transports. This result may partly explain the possible causes of a skewed sex ratio during development and at birth.
