If One of the Traits Mendel Studied Was Encoded by a Single

Multiple Choice

If one of the traits Mendel studied was encoded by a single gene with three alleles that produced different phenotypes, what would he have observed if he crossed all possible pairs of the three true-breeding lines in the F₁ and F₂ generations?

A) In each of the crosses, he would have observed two phenotypes in the F₁ generation.
B) Only a single phenotype would have been observed in the F₁ generation because only one allele can be dominant.
C) No evidence would exist for the law of segregation.
D) No true-breeding plants would have been produced in the F₂.
E) None of the answer options is correct.
