There are, however, a few irregularities. One is the appear- 

 ance in F3 and F4 of pink-flowered plants from light pink 

 parents, and another is the appearance of white-flowered plants 

 in the cross of Cnrrie X Mohawk. The single white-flowered 

 plant in F2 was covered with a mnslin bag for self-fertilizing 

 which may have suppressed the color, but the 21 whites from a 

 light pink parent cannot be thus accounted for ; they bred true 

 in the succeeding generations so far as flower color was con- 

 cerned.
