One question showed a pedigree with different cancers in the family down generations -- the cancers being Breast (age of onset (AOG) 28, 36 & 51), myxofibrosarcoma (AOG 48), medulloblastoma ( AOG 5) and rhabdomyosarcoma (AOG 8). The choices were:
anticipation, genetic heterogeneity, incomplete penetrance, multifactorial inheriatance and variable expressivity.
