Suppose that the following data was obtained when tabulating the kernels on several rows of an ear of genetic corn. Calculate the phenotypic ratio (this is similar to what you did in lab!)

Phenotype Number Ratio
Purple – starchy 81
Purple – sweet 33
White – starchy 29
White – sweet 10

a. Explain why these results indicate independent assortment of genes.

b. What would the phenotypic ratio be if these two genes were located on the same chromosome?
