Which of the following is the unit of transmission of hereditary traits in living organisms
Answer Details
The unit of transmission of hereditary traits in living organisms is genes. Genes are specific sequences of DNA that are located on chromosomes in the nucleus of a cell. They contain the instructions for the development and functioning of an organism, including physical traits such as eye color and height, as well as physiological traits like metabolism and immunity. During reproduction, genes are passed from parents to offspring through gametes, which are specialized cells that fuse during fertilization to form a new individual. Each gene has a specific location on a chromosome, and different versions of the same gene, called alleles, can exist at that location. Therefore, genes are the fundamental units of heredity that determine the traits and characteristics of all living organisms.
