this study aimed to identify genes that show signatures of selection for mutations in iranian native cattle breeds. the data consisted of genotypes for ~777962 snp markers of 90 animals from eight iranian native cattle breeds distributing over the country. therefore, the aim was to identifying divergently selected regions of the genome. study of population differentiation across the genome usin...

sperm dna is known to contribute one half of the genomic material to the offspring. the integrity of sperm dna is important in fertilization, embryonic and fetal development, and postnatal child well being. the nature has created multiple barriers that allow only the fittest sperm to reach and fertilize an oocyte. however, assisted reproductive techniques (art), like ivf and icsi, may allow spe...

The use of genomic selection for changing the growth curve shape of animals, acting simultaneously on the 3 parameters of a Gompertz growth curve, was studied using computer simulation. Results showed that genomic selection modified the growth curve. Responses to all selection criteria were accompanied with a correlated response in mature weight due to the high genetic correlations between matu...
