Answer:
1. The combined effect of inherited traits and the environment determines how an organism looks and behaves.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, freckles, dimples, tongue-roll, etc.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production.
Hence, the relationship between an inherited trait such as the traits mentioned above and the environment in which living organisms stay (ecosystem) is that, the combined effect of inherited traits and the environment determines how an organism looks and behaves.
