The offspring of the cross AA × aa are ________.

  1. a. all AA
  2. b. all aa
  3. c. all Aa
  4. d. half are AA and half are aa

Summary Introduction

Concept introduction: The parent genotypes if known will help to determine the possible genotypes of children based on the Mendelian monohybrid cross and dihybrid cross. The parents can be homozygous dominant or homozygous recessive or heterozygous individuals.

Explanation of Solution

Reason for correct answer:

The two parents are homozygous dominant AA and homozygous recessive aa. They will generate gametes that will have A and a, respectively. The two gametes with these genotypes will produce all offspring with the same genotype Aa. This is because the parents are homozygous dominant and homozygous recessive; therefore, these gametes though after undergoing independent assortment will be the same.

Option c. is given as “all Aa” and since all the offspring will have the same genotype Aa, the correct answer is option c.

Reasons for incorrect answer:

Option a. is given as “all AA”...
