Summary Introduction

To review:

On the basis of the data for the genotype, the types of gametes formed and their proportion, for the following pairs:

a. AABB

b. AaBB

c. Aabb

d. AaBb

One gene has the alleles A and a whereas another gene has the alleles B and b. A and B represent the dominant alleles while a and b represent the recessive alleles.

Introduction:

When a homozygous allelic pair divides, it forms the same genes with both coding either for dominant genes or for recessive genes. When a heterozygous allelic pair divides, it forms two genes that code for dominant genes and recessive genes. In the case of independent assortment, each characteristic separate into gametes independently when there are two or more characteristics to be inherited.
