Genetic Variation
Genetic variation refers to differences in the genetic makeup of individuals within a species. This diversity arises from mutations, gene shuffling during reproduction, and environmental factors. Genetic variation is essential for evolution, as it provides the raw material for natural selection to act upon. It allows populations to adapt to changing environments, improves survival, and contributes to the overall health of ecosystems. In humans, it manifests in traits such as eye color, height, and susceptibility to diseases, making each individual unique while still part of a larger group.

Genetic variation refers to the differences in DNA among individuals within a species. These variations can affect traits like appearance, health, and behavior. They arise from mutations, gene shuffling during reproduction, and other genetic processes. This diversity is crucial for evolution, as it enables populations to adapt to changing environments. Some variations may be beneficial, harmful, or neutral, influencing survival and reproduction. Overall, genetic variation plays a key role in the uniqueness of individuals and the resilience of species.

Genetic variation refers to the differences in DNA among individuals within a species. These differences can result from mutations, gene shuffling during reproduction, and other factors. Genetic variation is crucial for evolution and adaptation, as it provides the raw material for natural selection. It explains why some people may be more resistant to diseases, have different physical traits, or respond differently to medications. In essence, genetic variation contributes to the diversity of life, enabling populations to survive in changing environments by having a mix of traits.
