Assuming that independent assortment occurs during meiosis, what type(s) of gametes will form in individuals with the following genotypes?

  1. a. AABB
  2. b. AaBB
  3. c. Aabb
  4. d. AaBb

a.

Summary Introduction

To explain: The gametes formed in individuals based on independent assortment with the genotype AABB.

Concept introduction: Independent assortment is one of the laws proposed by Gregor Johann Mendel, a geneticist. Mendel proposed the law of independent assortment based on the results of dihybrid cross. Independent assortment is with regard to the genes of the loci. Locus refers to the location of the gene in the chromosome. In the homologous chromosome, two genes are present in two different loci. These two genes separate and enter two different gametes independent of the other. This process is called as independent assortment.

Explanation of Solution

The gametes formed are AB. The A and B genes assort independently of each other into different gametes. Here, the A allele and B allele are dominant...
