Colored and colorless seeds from homozygous B-Bolivia were planted, the resulting plants selfed, and ears scored for the proportion of purple colored kernels.

    • F2-a  The color of the seeds that were planted is indicated. Purple seeds were clearly distinguishable from colorless seeds, but were not necessarily the darkest seeds on the ear.

    • F2-b  The average of the proportion of colored kernels on each ear is given.

    • F2-c  The no. of ears that were counted and used to determine the mean.

    • F2-d  The proportion of colored kernels on the ears with the highest and lowest percentages in the sample.

    • F2-e  The probability that the difference between the ears derived from plants grown from purple and colorless seeds is due to chance variation. The probability was determined using the ANOVA method. In both cases, the differences between the plants grown from colored and colorless kernels were not statistically significant.
