Answer:

100%

Explanation:

Familial hypercholesterolaemia is a genetic disease characterized by greatly increased cholesterol levels. Due to this level, there are early manifestations of heart attacks, need for bypass surgery or angioplasty, among others. There are two types of familial hypercholesterolaemia: heterozygous and homozygous. The most common form is heterozygous, which affects 1 person in 250. It happens when only one parent has the defective gene. The child of a couple in this situation is 100% more likely to have blood cholesterol higher than normal.
