what is a trait vs gene
A single gene determines several traits and certain traits are determined by few genes. Some traits are observable (ex: hair color, skin color, eye color, etc.) and some are not (ex: blood group, risk for specific diseases, etc.). Observable traits also are called phenotypic traits.
A gene is a stretch of DNA that codes for a polypeptide via an RNA chain. These coded chains lead to âtraitsâ in an individual, such as eye color and blood type. A gene is the basic unit of heredity. An allele is a variation of a gene. Genes come in many different forms, or alleles, that lead to the encoding of different RNA chains and, therefore, different traits.
The term âGeneâ is lately evolved with the development of Genetics. Gene is a segment of DNA, which contains instructions to form proteins. Each gene has a specific sequence of base pairs, which determines the structure and function of a specific protein. Genes are the blueprints of all the traits in the body.
