title = "Some rare cases of chimerism in twin cattle and their proposed use in determining germinal cell migration",
abstract = "Three dizygotic, heterosexual twins with chimerisms carrying marker chromosomes are described. Phenotypic and cytogenetic methods were used to identify these animals. The occurrence of germinal cell migration causing gonad chimerism can be detected by the marker chromosome event under conditions described in this report.",

note = "Funding Information: studied and discussed frequently in recent years1. In embryo transfers for twin production in cattle chimerism is a potential problem because females with male twins are likely to become sterile10. Such females are unsuitable for breeding and have subnormal weight-gain efficiency compared to males. Freemartins among twins are generally identified by rectal palpation of adult animals8, as well as by the The authors are professor and graduate students, respectively, at the Swiss Federal Institute of Technology (ETH), Institute of Animal Production, CH-8902 Zurich.
