Answer:

Blue eyes are a recessive trait.

Step-by-step explanation:

The allele needed to produce blue eyes is recessive, whereas the allele for brown eyes is dominant. With that being said, Pat's parents must each carry an allele for blue eyes, thus passing the trait on to Pat.

Blue eyes are a recessive trait meaning Pats parents would both be heterozygous with one dominant gene and one recessive for each parent.
