Which term refers to the passing of genetic information to the next generation through an individual's own offspring?

• A. Direct fitness
• B. Offspring fitness
• C. Inclusive fitness
• D. Reproductive success

Answer: (A)

Direct fitness captures the genetic contribution to future generations that comes from an individual's own offspring. It reflects the genes passed directly through the person's children, forming the lineage from one generation to the next. In contrast, inclusive fitness combines this direct pathway with indirect contributions gained by helping relatives reproduce, since relatives share some of the same genes. Reproductive success describes producing offspring but doesn’t specify the genetic pathway they take to the next generation. Offspring fitness isn’t a standard term in this context. So the best fit for the described idea is direct fitness.
