Why is a pedigree chart useful in studying inherited diseases?
Answer and explanation
Correct answer: It shows how a trait passes through generations
A pedigree chart is a standard diagram used to record the occurrence of a trait or disease among family members across generations. By examining affected and unaffected relatives, scientists can identify patterns of inheritance and estimate whether a condition may be dominant, recessive, or sex-linked. It does not cure disease or remove genes, and it is not limited to measuring plants. Thus option A is correct.
