3. Marine clamworms have flat fleshy appendages used for respiration. This trait is controlled by a single gene with two alleles. The alleles display complete dominance/recessiveness. The dominant allele results in appendages with 3 lobes while the recessive allele results in appendages with 2 lobes. A female worm with 3-lobed appendages mates with a male with 2-lobed appendages. What is the genotype of the female if some of the offspring have appendages with 2 lobes?
