Heredity influences may be positive or negative.

• A. Inherited characteristics may have positive or negative influences on a child.
• B. Inherited characteristics are always positive.
• C. Inherited characteristics determine only physical traits.
• D. Heredity has no influence on temperament.

Answer: (A)

Heredity can influence a child in positive or negative ways. Genes contribute to a wide range of traits—including health, physical features, and temperament—and these inherited factors can lead to advantages in some cases and challenges in others. Some inherited traits may support strong health, resilience, or favorable temperaments, while others can increase susceptibility to certain illnesses or behavioral difficulties. Because inheritance isn’t purely good or bad, it makes sense that inherited characteristics may have positive or negative influences on a child. The idea that heredity is always positive, only affects physical traits, or has no influence on temperament doesn’t fit how genes actually contribute to development.
