A Homozygous Strain of Corn That Produces Yellow Kernels Is

question 14

Multiple Choice

A homozygous strain of corn that produces yellow kernels is crossed with another homozygous strain that produces purple kernels. When the F₁ are interbred, 280 of the F₂ are yellow and 70 are purple.

• A) If kernel color is controlled by a single gene pair with yellow dominant to purple, what would be the expected ratio of yellow to purple in the F₂?
• B) Do the observed data differ significantly from that expected in (a)? Explain your answer.
• C) Provide an alternative explanation for the inheritance of kernel color and evaluate it by comparing the observed data to that expected from your alternative hypothesis.
