STUDY OF SELECTIONS FOR SIZE, SHAPE, AND COLOR OF HENS' EGGS 215 



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 



it is seen that =- for the sire ranges from 3 to 18; for the dam, from 4 

 .t^r 



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



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

 .Lr 



for color, from 18 to 39.
