Astudent analyzed ears of corn that demonstrated two traits in the f2 kernels, purple or white colors and smooth or wrinkled shapes. a tabulation of 135 individual kernels gave the following results: purple and smooth = 75 white and smooth = 28 purple and wrinkled = 24 white and wrinkled = 8 how many phenotypes are present?

Four

Explanation:

As per given data, the cross was done to study the inheritance of two traits: color of kernels (purple or white) and shape of kernels (smooth or wrinkled). The F2 progeny consisted of total 135 kernels which exhibited four categories of phenotypes:

1. purple and smooth (75)

2. white and smooth (28)

3. purple and wrinkled (24)

4. white and wrinkled (8)
