Abstract:
Short tandem repeats have served as markers to locate loci controlling a quantitative trait. The present study was undertaken to identify genetic variants at the short tandem repeat region ETH10 in Vrindavani cows to determine their association with body weight at birth (BW) and thus to locate a segregating QTL for this quantitative trait in the population studied. 95 animals of the breed were genotyped for the STR and phenotyped for birth weight. The locus was found to be polymorphic with a total of 3 alleles present in the population. Least square analysis of variance did not reveal any significant effect of genotypes at ETH10 on body weight at birth in Vrindavani cattle.
