Answer :
A. A trait is a specific, heritable characteristic of an organism determined by its genotype and expressed as its phenotype, often aiding in survival and reproduction as an adaptation. Traits are subject to genetic inheritance and can increase an organism's fitness.
A trait is a specific characteristic of an organism that can be passed down from parents to their offspring. This characteristic, such as eye color or blood type, can be attributed to the organism's genotype, the genetic makeup that determines these traits. The visible expression of these genetic traits is called the phenotype, which includes both visible and physiological traits.
An important aspect of traits is that they can be an adaptation, which is a heritable trait or behavior that helps an organism survive and reproduce in its current environment. Adaptations are genetically based traits that have evolved over time, aiding the survival and reproduction of living things.
