Variation and Genetics

Short Definition

Variation is the difference in characteristics among individuals of the same species.

Genetics is the study of heredity and the transmission of traits from parents to offspring.

Detailed Explanation

Variation occurs due to genetic differences (mutations, recombination) and environmental factors. Genetics explains how traits are inherited through genes located on chromosomes.

Types of Variation

• Continuous Variation: Traits vary gradually (e.g., height, weight).
• Discontinuous Variation: Traits occur in distinct categories (e.g., blood group).

Importance

Variation is essential for evolution and adaptation. Genetics allows prediction of inheritance patterns and is fundamental in breeding, medicine, and biotechnology.
