Taste XLI.—Evpectation of seed classes resulting from the self-fertiliz ation of 
90 BULLETIN 754, U. S. DEPARTMENT OF AGRICULTURE. 
Table XLI shows the expected result of self-fertilizing the 16 
classes of zygotes in Table XL. When horny and waxy seeds are 
both present on a self-pollinated ear the expected proportion 1s 
always 3 horny seeds to 1 waxy, within the range of chance fiuctua- 
tion.

The following list shows the circles that would have four classes 
of seeds when self-pollinated, together with the degree of correla- 
tion expected : 
Circles Nos. 4 and 7, no correlation. 
Circle No. 10, correlation, colored and waxy, 0.744. 
Circle No. 12, correlation, colored and waxy, 0.880. 
Circle No. 18, correlation, colored and horny, 0.766. 
Circle No. 15, correlation, colored and horny, 0.570. 
The proportions in which the different degrees of correlation are 
expected are as follows: 
INOFCOrTe Ta GI OTA a eS eee ee ee ee re 4 ears. 
Correlation between colored and horny, 0.766_____________ 3 ears. 
Correlation between colored and horny, 0.570_____________ 3 ears. 
Correlation between colored and waxy, 0.744_____________ 1 ear. 
Correlation between colored and waxy, 0.380_____________ 1 ear. 
Table XLII shows the expected results of crossing colored horny 
with colored waxy plants when the ears obtained exhibit four classes 
of seeds, the expectation being that these ears are to have horny and 
waxy seeds in equal numbers.
