Which concept is used to study how traits are passed through generations within a family?

• A. Pedigree
• B. Natural Selection
• C. Gel Electrophoresis
• D. Restriction Enzyme

Answer: (A)

Pedigree analysis is the method used to study how traits are passed from generation to generation within a family. A pedigree is a family tree that records who is affected by a trait and how relatives are related, allowing you to identify patterns of inheritance and determine whether a trait is dominant or recessive, autosomal or X-linked, and who might be a carrier. This approach directly examines inheritance across generations in a family, which is different from natural selection that looks at how traits influence fitness in populations over time, or laboratory techniques like gel electrophoresis and restriction enzyme digestion that analyze DNA fragments rather than how traits are transmitted through families.
