Manifestations of Genetic Variation

Manifestations of genetic variation refer to the differences in traits and characteristics among individuals caused by variations in their genes. These differences can influence physical features like eye color, height, or metabolism, as well as susceptibility to certain diseases. Genetic variation arises from changes in DNA sequences, which can be inherited or result from mutations. The way these variations express themselves depends on interactions with other genes and environmental factors. Overall, genetic variation underpins the diversity seen within populations and influences health, appearance, and biological functions.
