GENETIC VARIATION
Biology
What is it??
Genetic variation is the difference or variety in genes. The fusion or outcome of different alleles. Genetic variation is good because some people are immune to different things and mixing the variation makes more people immune to different things.
Picturesss
Skin color
Skin color is varied because your skin will not be darker than the darker one of your parents and it will not be lighter than the lighter skinned parent.
Hair
Hair is based on genetic variation.
Eyes
Normally eye color is based on dominate trait but sometimes the color skips generations. Or sometimes the colors mix.
