The incidence of aneuploidy and mosaicism in 2,045 genotyped cattle blastocysts.

Abstract excerpt

Chromosomal abnormalities are the most common cause of developmental arrest in mammalian embryos. They can be present consistently in all cells of the embryo or occur as admixtures of karyotypically distinct lineages (mosaics). The estimated incidence of mosaicism ranges from 14% to 82% in human embryo biopsies at the blastocyst stage. In cattle, mosaicism is not well described at a whole-genome level, with...
