A 1/29 chromosome translocation was found in 10.2 p. 100 of a sample of 305 Nguni cattle. Investigations into the origin and spread of the translocation show a familial inheritance of the anomaly but give no indication as to the origin of the translocation. The high incidence was achieved despite the associated infertility and absence of artificial(More)
Following the discovery of the 1/29 chromosome translocation in Swedish artificial insemination (AI) bulls, cytogenetic evaluation of South African AI bulls was initiated. The present paper reports on the 269 bulls screened over the past 11 yr. The 1/29 chromosome translocation was found in Brahman and Brown Swiss bulls while chimerism was present in the(More)
Realistic modelling of breast deformation requires the breast tissue to be segmented into fibroglandular and fatty tissue and assigned suitable material properties. There are a number of breast tissue segmentation methods proposed and used in the literature. The purpose of this study was to validate and compare the accuracy of various segmentation methods(More)
A 1/29 chromosome translocation was found in a Brahman bull in artificial insemination service. In the subsequent investigation, it was established that most of the semen produced had been sold to commercial breeders. An extended pedigree showed that the translocation was introduced into South Africa by cattle imported from the USA. The anomaly was absent(More)
