INHERITANCE OF EGG PRODUCTION, SHOWN DIAGRAMMATICALLY 

 These diagrams show the production of four flocks in four different years. 

 Flock 4 is the pullet progeny of the best layers in flocks 1, 2 and 3. The hen 

 numbers are given at the left and the eggs laid by each at the right. The 

 dam is represented by the same line or symbol as the daughters, except in the 

 case of the black lines, where the ancestry of pullets is not given. A son of 

 034 was sire of all pullets except the daughters of 250, this hen being inbred 

 to her son.
