Provision of energy. Fats are a source of energy in the human diet, together with carbohydrates and proteins, the other two main macronutrients.
Dark fur color appears to be an adaptation for mice living in dark environments, as both the frequency of the characteristic and the allele that generates it have altered.

What is mutation?</h3>
A mutation is defined as a change in the sequence of genetic letters, called bases, within a molecule of DNA.
In a population, more offspring are born than can survive, resulting in competition among people. Individuals that possess a certain trait are more likely to live and/or produce more offspring than those who do not possess that trait. The context in which a species exists influences its selection. Characteristics that are advantageous in one setting may be detrimental in another.
New mutations cause black color.
- Fur color is controlled by many genes (4:29).
- Most genes are identical, but dark and light rock
- pocket mice differ in one gene (Mc1r; 4:55).
