Question

what is a pedigree?
shows relationships between family members and tracks a trait throughout generations
shows relationships between family members and tracks a trait between a mother and father
shows genetic relationships between siblings

Explanation:

A pedigree is a diagram that shows family relationships. It's used in genetics to track traits (like genetic disorders) across multiple generations. The second option only focuses on mother - father, which is too narrow. The third option only considers siblings. The first option correctly encompasses relationships between all family members and trait tracking through generations.

Answer:

shows relationships between family members and tracks a trait throughout generations
