20. The following pedigree shows a family with an unusually high incidence of skin cancer.

Parents are likely transmitting a deletion of a proto-oncogene to their children b. Parents are likely transmitting a deletion of a tumor suppressor gene to their children c. Loss of heterozygosity is likely to have occurred in affected individuals d. a and b e. ba
