A child's heredity are genes that are passed along from the parents. What do they determine?

• A. The child's brain development
• B. Hair color
• C. Height
• D. Eye color

Answer: (A)

Heredity means that traits are passed from parents to children through genes. These inherited characteristics are usually observable physical traits such as hair color, eye color, and height. Brain development, while influenced by genetics, also relies heavily on environment, nutrition, and experiences, so it isn’t determined by heredity alone. Among the options, hair color is a classic example of a trait largely controlled by genes, with eye color and height also strongly influenced by genetics but not immune to environmental factors. So the idea behind heredity best centers on these physical traits passed down, rather than brain development, which depends more on environmental factors.
