[Method]The segregation situation of feather color in the male and female offspring of Texan pigeon (♂)×American Silver King pigeon (♀)(TKYW) and American Silver King pigeon (♂) ×Texan pigeon (♀) (YWTK) was analyzed. [Result]The feather color of TKYW offspring was all slate gray. Among the offspring of YWTK, the feather color of the males was all slate gray, while the feather color of the females was all silver gray; and the ratio between different colors was 1:1 (P 〉 0.05). The F1 generation of YWTK was subjected to selfing, and the feather color of the male and female F2 generation was analyzed. It was found that the ratio of silver gray (male) to slate gray (male) to silver gray (female) to slate gray (female) was 1:1:1:1 (P 〉 0.05). On the basis of the above results, it could be preliminarily predicated that the feather color control genes of Texan pigeon are Z^BZB and Z^BW and those of American Silver King pigeon are Z^bZ^b and Z^bW. There is a cumulative effect on B which is dominant for b. [Conclusion] This study will better solve the problem of male and female identification of pigeon in the early period.展开更多
