Crossing Pea Plants: Mendel’s Study of Single Traits

Given the following matings, what are the predicted

genotypic ratios of the offspring?

  1. a. Aa × aa
  2. b. Aa × Aa
  3. c. AA × Aa

a.

Summary Introduction

To determine: The predicted genotypic ratio of the offspring produced between the cross of a parent with genotype Aa × aa.

Introduction: The alleles are inherited from the parents into the offsprings. The genotypic ratio represents the alleles that constitute the offspring while the phenotypic ratio represents the external features of the offspring.

Explanation of Solution

The cross between Aa × aa will produce the following offsprings:

GametesAa
a

Aa

(heterozygous dominant)

aa

(...

b.

Summary Introduction

To determine: The predicted genotypic ratio of the offspring produced between the cross of a parent with genotype Aa × Aa.

Introduction: The alleles are two variants of a gene. They are inherited from the parents to the offsprings. The genotypic ratio represents the alleles that constitute the offspring while the phenotypic ratio represents the external features of the offspring.

c.

Summary Introduction

To determine: The predicted genotypic ratio of the offspring produced between the cross of a parent with genotype AA × Aa

Introduction: The genotypic ratio is a means to represent the composition of the alleles that constitute the offspring while the phenotypic ratio represents the external characteristics expressed by the offspring.
