You decide to designate the twist allele as FT to distinguish it from the forked allele F. Using the following allele symbols, i

Answer:

FTFT, F, FFT (in order left to right)

Explanation:

The twist allele is FT, the forked allele is F. We are told there are pure lines, so this means they are homozygous. That means the parents are FF x FTFT.

The F1 generation is both twisted and forked (as can be seen from the image), suggesting the alleles are codominant (both are expressed).

In the F2, there are three different types of flowers, 2 matching the parental and 1 matching the F1 twisted, forked, and both.

The order from left to right is twisted, forked both. We know twisted is the genotype FTFT, and forked is the genotype FF. The both phenotype would have a copy of each allele, so would be FFT
