A trait in genetics refers to a specific characteristic or feature that is inherited and can be observed in an organism. Traits can be influenced by genes and their interactions, as well as environmental factors. They can manifest as physical attributes, such as eye color or height, or as behavioral tendencies. In the study of heredity, traits are used to understand how genetic information is passed from parents to offspring. This field includes the examination of dominant and recessive traits, providing insight into the genetic diversity within populations.
