The columbian restriction gene, Co, and early growth rate in the domestic fowl.
Studies were conducted on the effects of the columbian restriction gene, Co, on early growth rate in the domestic fowl. There were no statistically significant effects of the Co gene on body weights at 4, 6, and 8 weeks of age. The importance of these findings is discussed in relationship to the desired presence of the Co gene to enhance sex identification in sex-linked crosses utilizing the silver (S) and gold (s+) alleles.
