A summer-squash plant that produces disc-shaped fruit is crossed with a summer-squash plant that produces long fruit. All the F1 have disc-shaped fruit. When the F1 are intercrossed, F2 progeny are produced in the following ratio: 9 / 16 disc-shaped fruit : 6 / 16 spherical fruit : 1 / 16 long fruit. Give the genotypes of the F2 progeny.
