Heredity vs. Variation: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 29, 2023
Heredity is the passing of traits from parents to offspring, while variation refers to the differences among individuals in a population.
Key Differences
Heredity is the process by which genetic information is passed from parents to offspring. Variation, on the other hand, refers to the differences among individuals within a population or species.
Heredity ensures that offspring resemble their parents and belong to the same species. Variation allows for diversity within a population, which can be beneficial for adaptation and survival.
Genes play a crucial role in heredity as they carry the information that determines traits. Variation can occur due to differences in genes or environmental factors.
Heredity follows the laws of Mendelian inheritance, while variation can result from genetic recombination, mutation, or environmental influences.
Both heredity and variation are key components of evolution, as they contribute to the genetic diversity of a population.
