Igf-2 is maternally imprinted gene in mammals and in Martians. A Martian couple, B@sb&t (female – you can refer to her as B) and Sm@rj!p (male – you can refer to him as S), come to you for advice. Dwarfism related to a mutant copy of Igf-2 is fairly common in their families, although neither of them is affected. They request you help in determining their risk of having an affected child. Remember to calculate the best-case scenario, so if you can't tell the second allele of an ancestor assume that it is wild-type (but be careful that you really can't tell...). Separately report Sm@rj!p's chance of carrying an imprinted mutant allele and B@sb&t's chance of carrying an imprinted mutant allele. Then calculate their chance of having an affected child (be careful here!). The standard grading table will apply. B@sb&t Sm@rj!p
