 Inheritance within a population. 



Existence of diverse races. 



Ancestral correlations within a population. 

 Inheritance within single clones. 



Studied by the coefficient of correlation. 

 Ancestral correlations in Line 30. 

 Comparison with correlations in other races, 

 Studied by selection experiments. 



Selection experiments 1 and 2- Contradictory 

 results of two brief experiments in 

 mass selection. 

 Selection experiment 3 - Quick effect of 



individual selection based on progeny. 

 Selection experiment 4 - Decided effect of
