In a study of fruit shape in summer squash, Curcurbita pepo, two disc-shaped fruited plants heterozygous for two genes (AaBb) were crossed together. The geneticist be- lieves that a capital allele at both loci results in disc-shaped fruit (A B.), a capital at only one locus (A_bb or aaB_) results in sphere-shaped fruit, while no capital alleles (aabb) produces a plant with long fruit. If the 2 loci A and B are indpendently assort- ing, what is the phentypic ratio expected in the progeny of this cross? The resulting offspring are listed below. Are the data consistent with the Mendelian predictions of independent assortment and gene interaction (9:6:1 ratio)? Test with a significance of 0.05. Shape Number Disc 117 Sphere 90 Long 17 Total 224
