Question
A pure-breeding strain of squash
that produced disk-shaped fruits
was crossed with a pure-breeding
strain having long fruits. The F1 had
disk fruits, but the F2 showed a new
phenotype, sphere, and was
composed of the following
proportions: disk 270, sphere 178,
long 32. Propose an explanation for
these results, and show the
genotypes of P, F1 and F2
generations.
