“…The BGA1 chromosome is similar to the rob(1;29) of cattle, the most famous and widely spread chromosome abnormality in this species (Gustavsson 1969;Popescu and Pech, 1991;Di Meo et al, 2000). A combination of banding and FISH-mapping techniques with specific molecular markers mapping proximally to BTA29 and three SAT DNA (SAT I, SAT III and SAT IV) demonstrated that also the rob(1;29) of cattle originated by complex chromosomal rearrangements: a centric fusion translocation is followed by a pericentric inversion or chromosome transposition of a small proximal region of the p-arm (BTA29) to the proximal q-arm (BTA1) of the translocated chromosome (Chaves et al 2003;Di Meo et al 2006;Iannuzzi et al 2009).…”

A GTG-banding comparison between the chromosomes of gaur (Bos gaurus hubbacki, BGA, 2n = 56) and those of domestic cattle (Bos taurus, BTA, 2n = 60) was performed to establish chromosome homoeologies or differences between the two species. The two biarmed chromosomes of gaur (BGA1 and BGA2) were originated by centric fusion translocations between homoeologous cattle chromosomes 1/29 (BGA1) and 2/28 (BGA2). High resolution GTG-banding comparison between BGA1 and BTA1/BTA29 revealed that BGA1q differentiated from BTA1 by a paracentric inversion of a large and proximal chromosome region (BTA1q13-q32). To our knowledge, this is the first case of a bovid biarmed chromosome originated by centric fusion and paracentric inversion during karyotype evolution. The CBG-banding pattern showed clear C-bands in all autosomes, although the two biarmed pairs showed smaller C-bands, especially in BGA2. The results were discussed on the basis of previous results obtained in other bovid species, including the carriers of rob(1;29) of cattle, the most known and widely spread chromosome abnormality in Bos taurus.

Presumptive 1/29 Robertsonian translocation observed in the Argentinean Creole cattle breed

et al. 2003

-A cytogenetic investigation was carried out on 39 Argentinean Creole cattle (8 bulls and 31 cows) from the Experimental Station in Chamical (La Rioja, Argentine). Heparinised blood samples were cultured using a method of Moorhead et al. with some modifications. Karyotypes were established using a chromosomal digital analyser. A presumptive 1/29 Robertsonian translocation was found in one bull which had 2n = 59 chromosomes. The remaining animals appeared chromosomally normal. The 1/29 translocation has been diagnosed in other Creole breeds in America but never in Argentine. The Y chromosome of the sampled bulls had the typical sub-metacentric structure normally occurring in Bos taurus. It is suggested that programmes for genetic and reproductive improvement incorporate chromosomal analysis of bulls and cows with a high genetic value for natural and artificial breeding. Individuals with chromosomal abnormalities could then be eliminated, helping to assure the high fertility rates of this breed.

“…Chez le bovin, la translocation robertsonienne 1/29 (t 1/29), anomalie de structure, est l'une des plus largement répandues (Gustavsson et Rockborn, 1964 (Gustavsson, 1979), ont été identifiées comme porteuses de la t 1/29 (Popescu et Pech, 1991). Il n'est toutefois pas exclu que d'autres races soient porteuses de cette anomalie.…”
