Question

What is the typical duration of one human generation?

Options

• Approximately 10–15 years

• Approximately 30–35 years

• Approximately 5–10 years

• Approximately 20–25 years

Answer 1

Humans take approximately 20–25 years per generation, which makes controlled genetic studies impractical. This long generation time is one of the key reasons why pedigree analysis of family history is preferred over controlled breeding experiments for studying human inheritance.
