Screening of in vitro-produced cattle embryos to assess incidence and characteristics of unbalanced chromosomal aberrations

31 Jan 2023

Abstract excerpt

In cattle, pregnancy rates of in vitro-produced embryos are lower than those of in vivo-produced embryos. One of the reasons may be the increase in chromosomal aberrations due to in vitro maturation and fertilization of the oocyte. Currently, embryo transfer is commonly applied in nucleus cattle breeding programs, and the embryos are genotyped for genomic selection. Therefore, intensity data from SNP arrays can...
