What is the genotype of a heterozygote?

Options

  1. ATT
  2. BTt
  3. Ctt
  4. DTTT

Correct answer

B. Tt

Step-by-step solution

It is convenient (and logical) to use the capital and lower case of an alphabetical symbol to remember this concept of dominance and recessiveness. (Do not use T for tall and d for dwarf because you will find it difficult to remember whether T and d are alleles of the same gene/character or not). Alleles can be similar as in the case of homozygotes TT and tt or can be dissimilar as in the case of the heterozygote Tt
