Inheritable traits are best described as

• A. Responsible for characteristics
• B. Traits passed from parents to offspring
• C. Arise only in response to the environment
• D. Traits that disappear in future generations

Answer: (A)

Inheritable traits are traits that can be passed from parents to offspring through genetic material. Genes carried on chromosomes are inherited from both parents, so the offspring’s genotype includes a mix of parental alleles. This genetic information can be transmitted to future generations, which is what makes those traits heritable. The environment can influence how strongly or in what way a trait is expressed, but the underlying ability to pass that trait on remains, because it’s encoded in the genes.

Some descriptions don’t fit inheritance. Traits that arise only in response to the environment aren’t passed down genetically, so they’re not inherited. Traits that disappear in future generations aren’t carried in the genetic material, so they don’t persist through reproduction. A statement like “responsible for characteristics” is too broad and doesn’t specify how the trait is transmitted across generations.

So the best way to describe inheritable traits is that they are passed from parents to offspring through genetic material.
