Questio swer (5) For questios ad refer to the followig iformatio about hyperdactyly, a geetically iherited coditio. I humas the coditio of hyperdactyly (the possessio of twelve figers) is determied by the domiat allele (H) ad the ormal coditio by the recessive allele (h). The followig diagram shows a family tree i which some members of the family are hyperdactylous = hyperdactylous male = ormal male = hyperdactylous female = ormal female [dapted from Torrace] Paret 1's geotype is heterozygous homozygous recessive homozygous domiat lackig the mutat gee The geotypes of persos 1, 2 ad 3 i this family tree are HH Hh hh HH HH hh Hh HH Hh Hh Hh hh
