INHERITANCE IN HYDATINA 



77 



Hi from H. Females of the parthenogenetic line bred from a 

 high viability family in H3 were mated with males of the same 

 line May 11 to 20, 1912. From 23 such females were obtained 

 259 eggs, of which 125, or 48.2 per cent, hatched prior to June 

 19 (table 35). 



Comparison of Lj fro?n H with Hi from H shows that a single 

 selection for low viability within the high viability series was 

 entirely ineffective.
