“…The trend for Indian zebu diagnostic alleles (Indian zebu>African zebu>African taurine>European taurine) is supported by the history of introduction of zebu genes into Africa and Europe [10,15] and by investigations with other markers, which show a higher number of allele sharing between Indian and African zebu breeds [27,33,38]. In a recent study, Loftus et al [22] also recorded the presence of Indian zebu diagnostic alleles in some European cattle breeds, Hungarian Grey (2.2%) and Turkish Grey (10.4%).…”

-Genetic diversity, introgression and relationships were studied in 521 individuals from 9 African Bos indicus and 3 Bos taurus cattle breeds in Cameroon and Nigeria using genotype information on 28 markers (16 microsatellite, 7 milk protein and 5 blood protein markers). The genotypes of 13 of the 16 microsatellite markers studied on three European (German Angus, German Simmental and German Yellow) and two Indian (Nelore and Ongole) breeds were used to assess the relationships between them and the African breeds. Diversity levels at microsatellite loci were higher in the zebu than in the taurine breeds and were generally similar for protein loci in the breeds in each group. Microsatellite allelic distribution displayed groups of alleles specific to the Indian zebu, African taurine and European taurine. The level of the Indian zebu genetic admixture proportions in the African zebus was higher than the African taurine and European taurine admixture proportions, and ranged from 58.1% to 74.0%. The African taurine breed, Muturu was free of Indian zebu genes while its counter Namchi was highly introgressed (30.2%). Phylogenic reconstruction and principal component analysis indicate close relationships among the zebu breeds in Cameroon and Nigeria and a large genetic divergence between the main cattle groups -African taurine, European taurine and Indian zebu, and a central position for the African zebus. The study presents the first comprehensive information on the hybrid composition of the individual cattle breeds of Cameroon and Nigeria and the genetic relationships existing among them and other breeds outside of Africa. Strong evidence supporting separate domestication events for the Bos species is also provided.

“…The HBB X is heterogeneously distributed among native domestic cattle in Southeast Asia (Namikawa 1981). The HBB X is quite rare or absent in Indian zebu breeds (Naik et al . 1969) and not reported in European breeds.…”

The electrophoretic variation in bovine hemoglobin-beta (HBB) is one of the most investigated genetic markers. The presence of a unique HBB variant, HBB(X), in Southeast Asian cattle has been reputed as a sign of gene-flow from wild bovine species. In this study, we analyzed the DNA sequences of HBB genes in domestic and wild bovine species to verify this belief. Isoelectric focusing of HBB chain revealed that the HBB(X) in domestic cattle had dimorphism and was separated into HBB(X1) and HBB(X2). The HBB(X1) had the same DNA sequence of the common HBB variant in gayal (Bos gaurus frontalis), while some of the HBB(X2) were identical with that of Cambodian banteng (Bos javanicus birmanicus). As a result, we confirmed that the bovine HBB variants can be a good indicator of introgression between wild and domestic cattle. The HBB(X1) was always predominant to HBB(X2) in the continental populations, suggesting that the gaur had contributed to the gene pool of domestic cattle in this region much more than the banteng. On the other hand, the mitochondrial DNA analysis could not detect gene-flow from wild species. Autosomal markers that can trace the phylogeny between alleles are suitable for the assessment of bovine interspecific introgression.

“…The polymorphism could be located even at the lowest level of the taxonomic groups. In India haemoglobin studies have revealed many variants in man and in domestic animals (Sukumaran 1975;Naik et al 1969 ;Naik 1975). Wild rodent populations have yet not been touched so far by the Indian taxonomists to study the comparative account of the haemoglobin patterns by the electrophoretic techniques.…”

A comparison of the electrophoretic haemoglobin pattern of the commensal rodent species

The present paper reports the haemoglobin pattern by paper electrophoresis of seven rodent and one insectivore commensal species collected from Bombay-Pune region. Almost all the samples possess 1/1 type of haemoglobin which is slower in mobility than that of the normal human type. While the genus Bandicota possesses polymorphic haemoglobin types, it is quite surprising that Suncus murinus has the haemoglobin of anodic mobility as against its Soricidae counterpart's, Sorex's, haemoglobin showing cathodic mobility.
