    TLDR Pantaneiro sheep have more genetic diversity than Texel sheep, with potential for future research in Brazilian farming.
    The study analyzed 192 sheep, including 147 Pantaneiro and 45 Texel, to assess genetic diversity and identify genomic regions under natural selection. Pantaneiro sheep, native to Brazil, showed greater genetic variability compared to the more inbred Texel breed. The research identified outlier SNPs linked to traits like hair growth, tissue regeneration, and pigmentation, with the FGF12 gene noted for its role in hair growth. These findings highlight the genetic richness of Pantaneiro sheep, emphasizing their potential for future research and significance in Brazilian sheep farming, while the Texel breed served as a comparative group illustrating limited genetic variability in controlled environments.
