Answer:
Tt and tt
Explanation:
Dominant alleles are written with capital letters.
Recessive alleles are written with lowercase letters.
When an allele is <u>dominant</u>, the individual only needs <u>one</u> copy of it in order for the trait it codes to be expressed.
When an allele is <u>recessive</u>, the individual needs to have<u> two </u>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 taster
- tt, homozygous non-taster
The cross between a heterozygous taster with a non-taster would be:
<h2>
Tt x tt</h2>
