Inheritance of mean egg type 



The correlations shown in tables 14 to 22 and summarized in tables 23 

 and 24 indicate a distinct positive relation between the mean type of 

 either or both parents and the production of the offspring. In table 23 



r 



it IS seen that ^ for the sire ranges from 3 to 18; for the dam, from 4 



to 22; and for the average of both parents, from 8 to 39. In table 24 it 



J- 

 is seen that ^r ranges, for size, from 4 to 10; for shape, from 3 to 8; and
