Some rare cases of chimerism in twin cattle and their proposed use in determining germinal cell migration
Swiss Federal Institute of Technology (ETH), Institute of Animal Production CH-8902 Zürich
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.
