Question

Suppose the two possible alleles for the height gene are tall and short. If short is recessive to tall, provide the symbol representation and the phenotype for each of the genotype for this trait.

Answer 1

Phenotype - short , Tall

Genotype - tt (short) , TT or Tt (tall)

Explanation:

In Mendelian Genetics, Dominant traits are represented by capital letters and Recessive traits are represented by small letters.

So if height is the character considered, then the traits would be short and tall.

Tall is the dominant phenotype and short is the recessive phenotype.

The alleles of the gene for height are T and t.

The genotype for Tall trait is TT or Tt.

The genotype for short trait is tt.

Therefore, the symbol representation of phenotype (Tall) is TT or Tt and for phenotype (short) is tt.
