Breаst cаncer shоws аutоsоmal dominant inheritance with incomplete penetrance among females who inherit one affected BRCA2 allele. 30 of 50 females who inherited a BRCA2 mutation developed breast cancer by 80 years old. Eddie is heterozygous (i.e., one normal BRCA2 allele and one affected BRCA2 allele), but his partner does not have a BRCA2 gene mutation. What is the probability that Eddie’s daughter will develop breast cancer by age 80? (HINT: This is the probability that his daughter inherits an affected BRACA2 allele AND the penetrance of the phenotype, which was calculated in Q36).
