Answer:

person 1 in row 3's genotype AA or Aa

Explanation:

the trait is recessive (given) which means in order to have it, you must obtain both alleles. in the pedigree, shaded shapes indicate people who have the trait, but person 1 in row 3 is not shaded so their genotype must be AA (dominant) or Aa (dominant leading) and their phenotype would not express the trait, because the dominant allele will "take over"
