Some mammals have genes for fur color that pro- duce pigment only when the outside tempera- ture is above a certain level. This pigment pro- duction is an example of how the environment of an organism can (1) destroy certain genes (2) cause new mutations to occur (3) stop the process of evolution (4) influence the expression of certain genes

In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). This change in skin color provides evidence that (1) ultraviolet light can cause mutations (2) gene action can be influenced by the environment (3) the inheritance of skin color is an acquired characteristic (4) albinism is a recessive characteristic

Labrador retriever’s fur color is controlled by two alleles, E and B. The B/b gene codes for hair pigment, while the E/e gene controls whether or not pigment of any color will be show in the hair.
