With an association between one of two factors for color and endo- 
sperm texture, a variety of zygotic ratios may be obtained, even 
though the assumption is made that the gametic reduplication is only 
of the series 3-1-1-3. Table XXXV gives the degrees of correla- 
tion expected between endosperm texture and aleurone color where 
the assumption is made that the reduplication in the gametes between 
endosperm texture and a factor for color (C’) is of the series 3-1-1-3. 
The minus sign is used to indicate a correlation between colored aleu- 
rone and waxy endosperm; the other correlations are between colored 
aleurone and horny endosperm. Column 4 gives the gametic com- 
position of the two parents which, when crossed, give the zygotic 
classes shown in column 5 and the correlations shown in column 1. 
The letters Cand F represent color factors. H represents the domi- 
nant character, horny endosperm, and h waxy endosperm.
