Tt and tt

Explanation:

Dominant alleles are written with capital letters.

Recessive alleles are written with lowercase letters.

When an allele is dominant, the individual only needs one copy of it in order for the trait it codes to be expressed.

When an allele is recessive, the individual needs to have two copies of it in order for the trait it codes to be expressed.

Given the gene T/t, which determines the ability to taste PTC, there are 3 possible genotypes for a person:

TT, homozygous taster.Tt, heterozygous tastertt, homozygous non-taster

The cross between a heterozygous taster with a non-taster would be:

Tt x tt
