Using the Punnett square method, the genotype of the offspring is H'H, H'H, H'H, H'H.
Since the parents show incomplete dominance, the genotype of the offspring is shown below:
Parent 1 gamete: H' H'
Parent 2 gamete: H. H
Offspring: H'H, H'H, H'H, H'H
Therefore, the genotype of the offspring is H'H, H'H, H'H, H'H.
