Which chart tracks which family members have a trait?

• A. Family Tree
• B. Genogram
• C. Pedigree
• D. Cladogram

Answer: (C)

Tracking how a trait appears across generations in a family is the main idea. A pedigree is built for that purpose: it records who has the trait in each generation and shows how related individuals are, using simple symbols for sex and shading to indicate presence of the trait. This setup lets you spot inheritance patterns—whether the trait seems to run in families, and if it looks dominant, recessive, or possibly sex-linked—by following affected individuals through different generations. Other charts aren’t as suited for this specific purpose: a family tree shows familial relationships and ancestry but not who has the trait, a genogram adds broader health and relationship details used in counseling, and a cladogram maps evolutionary relationships among species rather than how a trait spreads within a single family.
