“…Breeding tests with a chimeric bull failed to produce an unexpected deviation in the sex ratio of the progeny (Teplitz et al 1967). The progeny of a bull which exhibited exclusively female leucocyte did not deviate from a normal sex ratio when observed over a five year period (Kosaka et al 1969). On the other hand, Dunn et al (1968) observed 71% of the females among the progeny of one chimeric bull.…”

ContentsThis communication describes cases with chimeric patterns that consisted of cells with hO,XX and 59,XX,t(l:29) in homosexual twin cows and a dam having heterozygosity for 1/29 Robertsonian translocation. The calves from one partner twin had 1/29 translocation only. On the other hand, calves from another partner twin had normal cells only. From the results obtained, it is proposed that germ cells would not migrate in bovine freemartin syndrome. Inhalt Chromosomenanalyse in gleichgeschlechtlichen Zwillingskiihen und in Nachkoinmen mit Chimarismus fur 1/29 TranslokationEs wird uber gleichgeschlechtliche Zwillingskiihe berichtet, die ein chimarisches Verteilungsmuster fur 60,XX und SY,XXt (129) in ihren Zellen aufwiesen und uber eine Kuh, die heterozygot fur 1/29 Robertson'sche 'lranslokation war. Nur die Kalber des einen Zwillingspartners hatten eine 1/29 Translokation, wahrend die Nachkommen des anderen Zwillingspartners normale Zellen aufwiesen. Aus diesen Ergebnissen wird gefolgert, dalj Geschlechtszellen beim Rind beim Freemartin Syndrome nicht uberwandern.

“…Lodja (1972) reported a sex ratio of .40 for a heterosexual bull used for artificial insemination in Czechoslovakia, and DeGiovanni et al (1975) reported on an XX/XY chimaeric Holstein-Friesian bull that had sired 116 females out of 148 total progeny. A heterosexual twin Holstein bull studied by Kosaka et al (1969) produced 820 male and 979 female calves in 5 years, for a sex ratio of .46. Dunn et al (1979) reported that a chimaeric XX/XY bull had an offspring sex ratio of .29 based upon 48 calves.…”

Reports are reviewed in which genetic differences for sex ratio of offspring were found among breeds, breed crosses, strains, lines, line crosses, families or individuals. Although reports in which genetic variation could not be identified outnumber those in which it could, important genetic variation does exist in at least some populations. The direct or correlated response of sex ratio to selection is reviewed. Again, results are equivocal, but there is ample evidence that sex ratio will respond to selection in at least some populations of laboratory organisms. Segregation distortion in the mouse and in Drosophila is examined. Segregation distortion occurs when a heterozygous male mated to a homozygous female does not produce the two offspring types in equal proportions and the disparity cannot be accounted for by sampling or differential mortality. Although the most well-known systems have no effect (in the mouse) or only a moderate effect (in Drosophila) on sex ratio, systems in which sex ratio is subject to segregation distortion are known to exist in insects and could exist in mammals. Finally, the possibility is discussed that XX/XY chromosome chimaeric bulls, born co-twin to a heifer, might produce a preponderance of heifer progeny. A few reports suggest this might be the case, but other research is not in agreement.

To investigate the chemeric condition of bulls by cytogenetic analysis the present study was conducted. The whole blood culture, cell harvesting, conventional Giemsa staining and GTG banding were performed for the chromosomal studies. During cytogenetic investigation on 200 buffalo bulls, 3 young bulls exhibited sex chromosomal chimerism (XX/XY) in their blood cells. Hundred metaphase fields were screened for each bull. Cytogenetic studies on chimeric bulls indicated unusual higher ratio of XX chromosomes in 3 bulls. The fertility status of these bulls are not known as they are young and not in semen collection. As documented, the fertility of chimeric bulls is not grossly affected and the condition is not inheritable. Hence, the bulls may be used for breeding programmes if their semen quality is good.
