If a particular inherited trait appears in every generation of a family how can it be studied?
Answer and explanation
Correct answer: By a family tree
A family tree, also called a pedigree, records the occurrence of a characteristic among members of successive generations. By comparing parents, children, and other relatives, it helps researchers trace whether a trait tends to be transmitted and infer possible inheritance patterns. Therefore option A is correct. Fossil fuel, the water cycle, and digestion concern energy resources, environmental processes, and nutrition respectively, not the transmission of a family trait.
