| Abstract: | The present study was conducted to examine
genetic diversity, genetic differentiation and genetic relationship among Gir,
Deoni and Kankrej cattle breeds using microsatellite markers. The number of
alleles observed at different loci ranged from 5 (HEL5) to 8 (CSRM60) with a
total of 46 alleles across three breeds. The overall heterozygosity and
polymorphic information content (PIC)
values were 0.730 and 0.749, respectively. Nei’s standard genetic distance was
least between Gir and Kankrej and highest between Deoni and Kankrej. In the
analyzed loci, an overall significant deficit of heterozygotes across these
breeds was found and it could be due to inbreeding within breeds. The overall
genetic differentiation (FST)
among breeds was moderate, but
significantly different. All loci, except INRA035, contributed significantly to
the overall differentiation. The highest FST
values were found in HEL5 and lowest in INRA035. The overall Nem
value indicated a high rate of genetic flow between the breeds, which is in
agreement with their origin of close proximity in the geographical area. |
