INHERITANCE OF WAXY ENDOSPERM IN MAIZE. 93 
There are three classes of waxy seeds with which circle 15 may be. 
crossed that will result in ears with four classes of seeds. These 
seeds are represented by circles 8, 14, and 16 in Table XL. Circle 8 
can be eliminated, since a cross between it and circle 15 would result 
in an ear with no correlation. The choice lies between 14 and 16. 
The result of crossing circles 15 and 14 would be an ear with a cor- 
relation approximating 0.615 between C and H. This is a fairly 
close approximation to the 0.653+-0.039 obtained with ear No. 1860, 
but the correlation of 0.259+0.12 obtained with the exact reciprocal 
of ear No. 1860, namely, No. 1874, is a very close approximation to 
the expected 0.270, when circles 15 and 16 are crossed. In this case, 
as is Shown on page 90, the expected ratio of colored to white seeds 
is 9 to 7, while on the ear concerned, No. 1874, the colored seeds are 
approximately three times the number of white seeds. The corre- 
lation of 0.259 certainly can not be looked upon as a chance fluctua- 
tion from the correlation 0.615 expected when circles 15 and 14 are 
crossed. A case parallel to this is found in the cross Dh 334. The 
colored waxy parent pollinated by the colored horny is represented 
by ear No. 1902, the exact reciprocal is ear No. 1917, and the self- 
pollinated colored horny parent is ear No. 1918 (Table XLV).
