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.
