Indicine cattle breeds are adapted to the tropical climate, and their coat plays an important role in this process. Coat color influences thermoregulation adhesion of ectoparasites may be associated with productive reproductive traits. Furthermore, is used for breed qualification, breeders preferring certain colors. The Gir characterized by a wide variety Therefore, we performed genome-wide association studies identify candidate genes cattle. Different phenotype scenarios were considered analyses regions identified on eight chromosomes. Some many influencing cattle, which was found polygenic trait. have been white spotting patterns base other species. In addition, possible epistatic effect determination suggested. This first published study that genomic listed findings provided better understanding genetic architecture trait will allow guide future fine-mapping development markers selection.
