Answer:

A person with two copies of "t" inherited one from their mother and one from their father

Explanation:

This is because both the father and the mother are carriers of "t" alleles which is a bent thumb. When the parent mate, the father donate one t and the mother too donate one t allele, therefore the person will inherit bent thumb from them.
