Summary Introduction

To determine: The ratio of “T” to “t”allele in the F2 progeny and identify if the ratio is similar to the phenotypic ratio 3:1.

Introduction: An allele is defined as a variant of a gene responsible for coding a specific character. There are atleast two different alleles for each phenotypic characteristics. One allele is dominant while the other form of the allele is recessive. The interaction between the alleles is responsible for different phenotypic traits. These interactions can produce three types of genotypes: homozygous dominant, heterozygous and homozygous recessive.
