One example of a polygenic trait is the length of ears of corn. Suppose that the shortest ears of corn are about 6 cm, while the longest ears of corn are about 18 cm. The following table represents the F2 offspring of a test cross between a short-eared and a long-eared corn plant: Length of 5-7 cm 8-10 cm |11-13 14-16 |17-19 ears of corn cm cm cm Number of 20 F2 offspring 83 |126 85 21 What are the ratios of F2 offspring that express the extreme short or long-eared phenotype? Based on the ratios above, calculate the number of polygenes likely to be involved in ear length for corn.

Heavy bloom is dominant to light bloom, skin that is green is dominant to skin that is yellow, and fruit with a long shape is dominant to ovate shape. A plant that is true-breeding for the dominant traits was crossed to a light, yellow and ovate fruit. The F1 plants were then testcrossed to light, yellow and ovate fruit.
