Summary Introduction

To determine:

The genotype of ${\text{F}}_{\text{2}}$ progeny in the cross of summer squash plant which produces disc shaped fruits and summer squash plant which produces long fruit.

Introduction:

There are two varieties of summer squash; one produces longer fruits and one produces fruits with disc shape. If the cross is made between these two varieties all ${\text{F}}_1$ plants produces disc shaped fruit. When the ${\text{F}}_1$ progeny are self-crossed, the ${\text{F}}_{\text{2}}$ progeny are produced in ratio; $\frac{9}{16}$ disc shaped fruit, $\frac{6}{16}$ spherical fruit, and $\frac{1}{16}$ long fruit.
