Gene Theory

Gene theory is the scientific concept that genes are the fundamental units of heredity in living organisms. Genes, made of DNA, contain the instructions for building proteins, which perform essential functions in the body. They determine traits, such as eye color or height, and are passed from parents to offspring. Variations or mutations in genes can lead to differences within a species and even contribute to evolution. Overall, gene theory helps us understand how traits are inherited and how organisms develop and function.
