Abstract

Cytogenetic investigations were made concerning the presence of the 1/29 and 14/20 Robertsonian translocations in the Charolais and Simmental cattle breeds in the United States and Canada. The results indicated that positive cases were present in some of these beef cattle populations. Of the 659 Charolais cattle tested, 142 (22%) were 1/29 CF translocation positive. Of the 353 Simmental cattle tested, 138 (39%) were 14/20 CF translocation positive. For both breeds these results are not representative of the prevalence of the chromosomal aberration in the entire population.

A small farm is nestled among rolling hills, fields stretching across a curving road that disappears between dark green trees. The barn is a cheery red color with a tin roof.
