Question
is this statement correct To inherit the disease, the child only needs 1 copy of the defective to show disease symptoms, which would be 50%.
Solution
The statement is partially correct, but it depends on the type of inheritance pattern of the disease.
In the case of autosomal dominant diseases, yes, a child only needs one copy of the defective gene to show disease symptoms. This is because the disease-causing allele is dominant and overrides the normal allele. If one parent has the disease (and therefore has at least one copy of the defective gene), each child has a 50% chance of inheriting the disease.
However, in the case of autosomal recessive diseases, a child needs two copies of the defective gene (one from each parent) to show disease symptoms. If both parents are carriers (meaning they each have one copy of the defective gene but do not show symptoms), each child has a 25% chance of inheriting the disease.
So, the statement is correct for autosomal dominant diseases, but not for autosomal recessive diseases.
