Chapter 3.3, Problem 36AQP

a.

Summary Introduction

To determine:

The phenotypes and the expected proportions of progeny in ${\text{F}}_2$ obtained from the self cross of ${\text{F}}_1$ (obtained by the cross between plants with homozygous for dull, orange fruit and bitter cotyledons and plant with glossy, cream fruit and non bitter cotyledons).

Introduction:

The cross between a homozygous dull (DD), orange fruit (RR), bitter cotyledons (BB) and plant with glossy (dd), cream fruit (rr) and non bitter cotyledons (bb) will give rise to progeny with dull, orange fruit and bitter cotyledons as the trait dull (D) is dominant over glossy (d), orange fruit (R) is dominant over cream fruit (r) and bitter cotyledons (B) is dominant over non bitter cotyledons (b).

Summary Introduction

To determine:

The phenotypes and the expected proportions progenies obtained from cross between ${\text{F}}_1$ ($\text{DdRrBb}$) plant with a glossy, cream fruit and non bitter cotyledons.
