What best describes genetics?

What best describes genetics?

• A. Way of inheriting traits that are inherited independent of one another
• B. Traits always inherited together
• C. Not inherited
• D. Only physical traits inherited

Answer: (A)

Genetics is the study of how traits are passed from parents to offspring through genes. It explains the patterns of inheritance you see in families, including why some traits seem to separate independently across generations (because genes on different chromosomes assort independently during reproduction) and why other traits may appear together when genes are linked on the same chromosome. It isn’t about traits that aren’t inherited or only about physical traits—their inheritability applies to many kinds of characteristics, including biochemical tendencies and other heritable differences. So the description that emphasizes inheriting traits in a way that they can be inherited independently of one another best captures what genetics is about.
