WebNov 1, 2024 · In addition, Liu et al. (2010) evaluated the Dongxiang black chicken breed skin color from hatching to 112 d and reported that TYR gene expression was greatest at the hatching, and the MC1R gene expression was the greatest at 28 d of age and subsequently decreased. From reducing the expression for genes involved with melanin … WebMay 16, 2013 · GWAS detection of SNPs associated with HVP. A GWAS was used to dissect the genetic factors associated with HVP. SNP additive effect analysis identified several regions that were significantly (P < 6.28 × 10-7) associated with HVP on both GGA1 and GGA20 (Figure 2A).As shown in Table 2, 20 SNPs with additive effects with genome …
Expanded Analysis of Pigmentation Genetics in UK Biobank
WebFeb 2, 2024 · The genetics of pigmentation is an excellent model for understanding gene interactions in a trait almost entirely unaffected by environment. We have analysed pigmentation phenotypes in UK Biobank using DISSECT, a tool which enables genome-wide association studies (GWAS) whilst accounting for relatedness between individuals, and … Webyellow skin, white skin, and black skin chickens were 0.81, 0.35, and 0.56, respectively. The results showed that the yellow skin phenotype of the evaluated birds has not been under selection, and that the BCDO2 gene in black skin chickens, evolutionally may undergo a transition phase from yellow to white skin chicken. We concluded that, the … puu ilo jyväskylä
