Chapter 11.2, Problem 3CC
Summary Introduction

To determine:

The fraction of off springs with a genotype consisting of at least two alleles in homozygous recessive state from the cross between PpYyIi and ppYyii.

Concept introduction:

A cross in which alleles for three characters are used is called a trihybrid cross. In a trihybrid cross, all the three laws of inheritance given by Mendel are followed which are: law of dominance, law of segregation and law of independent assortment.

WHAT IF? List all gametes thatcould be made by a pea plantheterozygous for seed color, seedshape, and pod shape (YyRrIi; seeTable 14.1). How large a Punnettsquare would you need to drawto predict the offspring of a selfpollination of this “trihybrid”?
WHAT IF? If the parental (P generation) flies had been true-breedingfor gray body with vestigial wings and black body with normal wings, whichphenotypic class(es) would be largest among the testcross offspring?
Problem: A homozygous tall, homozygous white flower plant crosses with a homozygous short, homozygous purple flower plant. We know that the purple and tall flowers are the dominant traits.  Show your work.   What are the phenotypes of the offspring?
