 Comment. — The children show the usual variability that arises from this 



type of mating (D : Wat.). 



Mating 2. Fleshy x Heterozygous Fleshy Parents. 



This includes matings between a heterozygous parent of fleshy 

 build and a very fleshy (or fleshy) parent of fleshy stock; a back-cross 

 to the more nearly dominant type. 



The matings of this type are as shown in table 33. 



A = 40.48 ± 0.57 



S. D. 6.36 ± 0.41. 



These 9 matings yielded 56 children, with the following percentage 

 distribution: 4 S, 25 M, 37 F, 34 VF. The 6-zygotic-factor 

 mating 5X3 (both possibilities) gives a percentage distribution of 

 3 S, 25 M, 43 F, 28 VF, which approximates that found.
