Variations, traits
Not all members of a species are the same. Every species exhibit variations. Traits, like eye color, are passed from parent to offspring.
Genetic variation is the subtle differences in the DNA sequence in each individual’s genomes. Genetic variation results in various forms or alleles of genes that determines distinct traits such as eye color, skin color, shape of face, and hair color that can be passed on from parents to offspring.
