Series 4. Grosses between various Breeds which lay different 

 coloured Eggs. 



This series of experiments was undertaken with the intention of 

 observing the influence of egg-characteristics belonging to the breed 

 used as male parents towards the characteristics of Fi eggs. 



(1) Reciprocal matings between Chinese whites from the Joken 

 and Kainei districts and Japanese univoltine breeds, " Aojiku " and 

 "Chusti." 



Egg-colour of the Chinese breeds: dark-slate, more or less shaded 

 with green in various degrees, sometimes without any green shade. 

 We call this colour Chinese normal colour. 



Egg-colour of the Japanese breeds (Figs. 1, 3, and 11): brownish 

 slate, more or less shaded with pink or purple. This is the ordinary 

 egg-colour of Japanese breeds.

 and the extracted normal-egged breed (Ivg), or the univoltine white,
