چکیده

selective signatures in whole genome can help us to understand the mechanisms of selection and to identify the genomic regions that have been under natural or artificial selection during long years. the objective of this study was to identify the genomic regions that have been under artificial and natural selection in baluchi and zel sheep breeds. 143 sheep from baluchi (n=96) and zel breeds (n=47) have been genotyped using the illumina ovine snp50 beadchip. unbiased method of weir and cockerham’s fst (theta) was used to detect the selection signatures in the r package. the results revealed seventeen genomic regions on 3, 4, 5, 7, 10, 11, 12, 13, 15, 18 and x chromosomes. bioinformatics analysis demonstrated that some of these genomic regions overlapped with reported genes included in the development of the skeletal system and tail, cytology cells, immune system, sugar and energy metabolism and reproduction traits such as rps6ka3, hoxb9, espl1, aaas, fndc3a genes. the results of the present study and the identified genomic regions can play an important role in study of the effect of the selection on population differentiation in two baluchi fat-tailed and zel thin-tailed breeds and subsequently, would direct us to identify the genomic regions associated with traits differentiate these breeds.

Polymorphism of the Melatonin Receptor 1A Gene and Its Association with Litter Size in Zel and Naeini Sheep Breeds

The influence of melatonin receptor 1A gene on litter size was studied in 150 ewes from Zel (n=100) and Naeini (n=50) sheep breeds. Two restriction fragment length polymorphism (RFLP) analyses were done to determine all genotypes occurring by variations at MnlI and RsaI restriction sites. The M and C were the most frequent alleles in both of these breeds. The MM genotype was predominant in Zel ...
