A woman has an autosomal dominant form of postaxial polydactyly. Assuming that you have not examined any other family members to determine whether they have postaxial polydactyly, what is the probability that her second cousin is also affected with this fully penetrant disorder?

I don't think its possible to calculate as there isn't enough information about the genetic status of family members.
What percentage of genes/chromosomes are shared between:
parent-child
siblings
cousins
uncle-niece
second cousin
uncle-nephew,aunt-niece/nephew??????
