Phenotypic Variation | Overview, Types & Causes

The Importance of Genetic Variation

Individuals with red hair often have a genetic variation in the melanocortin-1 receptor (MC1R) gene, which is responsible for producing the pigment that gives hair its red color. This genetic variation can also affect how the body responds to certain types of anesthesia and pain medications. There is a study which shows on average those with red hair may require around 20 percent more anesthesia. Of course an individual's response to anesthesia is also influenced by many factors including geneti

Genetic Variation

SOLVED: 1. Explain the importance of phenotypic variation on the phrase 'survival of the fittest' and indicate the impact this genetic variation has on evolution. 2. Detail the major differences between the steps of mitosis and meiosis. Show which process leads to increased genetic diversity by describing specific steps.
