NON-BARRED SPL4SHED FEMALE 



Non-barred splashed female (Kansas 1672). Third of the four kinds produced by a cross 

 between a splashed Andalusian male and a White Wyandotte female. (Fig. 15.) 



splashed males (Fig. 13), (2) barred 

 blue males (Fig. 14), (3) non-barred 

 splashed females (Fig. 15), and (4) 

 non-barred blue females (Fig. 16). 



As previously suggested (Lippin- 

 cotf), the splashed Andalusian is ho- 

 mozygous for a dominant factor for 

 black pigment and for another domi- 

 nant factor which, acting on black pig- 

 ment, renders it bluish-grey in appear- 

 ance. It lacks another dominant fac- 

 tor which is present in self blue, self 

 black, and some self white races, which 

 extends black pigment, if present, into 

 all parts of all feathers of the body, 

 giving a self color. 



These last two factors may be true 

 allelomorphs (i. c, occupying identical 

 loci of homologous chromosomes) or 



each may be closely linked to the re- 

 cessive allelomorph of the other, a point 

 as yet undetermined. 



Assuming that the latter is the case, 

 the genetic formula of a splashed An- 

 dalusion male, with regard to the char- 

 acters in question is — 



PP (Re) (Re) bb 



where P = black pigment 



P = white (no pigment) 

 (Re) = blue in presence of P (self blue if 

 heterozygous [(Re)(rE)], splashed 

 if homozygous [(Re) (Re)] 

 (rE) = self black if homozygous [(rE)(rE)] 

 In presence of P, blue if heterozy- 

 gous [(rE)(Re)] in presence of P. 

 B (sex-linked) = barring in presence of P. 

 b (sex-linked) = non-barring. 



b = indicates lack of synaptic mate of B 

 or b in the female
