Webgro = recessive allele for clumped bristle position. Ro = dominant allele for normal eye morphology. ro = recessive allele for rough eye morphology. From the parental cross, we know that the female fly is homozygous for gro (GroGro) and the male fly is homozygous for ro (roro). Therefore, their F1 offspring are all heterozygous for both traits ... Webheterozygote shows both the "dominant" and "recessive" phenotype----both alleles act as dominant allele and show up independently (such as with spots) ... Two O alleles must be present for the person to have type O blood-----the A and B alleles are codominant. If a person receives an A allele and a B allele, their blood type is type AB.
