280 Secondary Sexual Characters in Pheasants 



In the case of leg colour, we also find evidences of hybridism 

 through all four generations, but in some cases there is distinct 

 segi-egation of the colour of the parent species. Thus : —

Number of birds examined :

(3) Six months old F. "BBA": ? ? (2) bright scarlet, (1) rose 

 colour. 



(26) Chicks F, ''BBBA": (20) like " B" ?, (4) mosaic, (2) like 

 "A" ?. 



(12) Chick stage, five weeks old, F^ " BBBA " inter se : (9) pale 

 red, (3) mosaic of dull dark red and pale bright red. 



(5) Adult stage F, "BBBA " inter se ? ? " GMCKF" bright rose 

 like the Silver ^ transmitted by female parent. 



Thus we see that F^, F^, and F^ generations showed hybrid leg 

 colour. 



The early records in 1911 of Fi " BBBA" inter se notice distinct 

 evidence of Mendelian segregation even in the chick stage. The leg 

 colours of the two parent species are as follows: Silver % pale scarlet; 

 Silver cT bright rose ; Swinhoe % and cf dull dark red. At five weeks 

 old the leg colour of the 12 F^ " BBBA " infer se is recorded a.s nine (9) 

 pale bright red legs and three (3) mosaics of dull dark red and pale 

 bright red, also at two months old notes were made of a strong brown 

 colour staining the immature plumage of several F4 " BBBA " inter se 

 ? ? and these Swinhoe characters would appear to have been transmitted 

 through Fj, F„ and F.^, ^ ^ from the one dose of Swinhoe ^ in the first 

 cross. The hybrid characters of i'^, F.^ and F.^ %% must also have been 

 derived from the males in each generation.
