Fertilization of gametes containing chromosomes with duplications or deletions often results in children with disabilities. What is the probability of a couple, where the male is karyotypically normal and the female has a pericentric inversion in a heterozygous condition, producing a child with disabilities if crossing over took place within the pericentric inversion in 26% of meiotic divisions? (Assume fertilization with a gamete containing duplicated or deleted chromosomes results in disabilities).
