Question

select the correct answer.
duplication in the gene encoding a protein involved in vision has enabled humans to acquire trichromatic vision, which is the ability to distinguish between red, green, and blue colors. which type of mutation is this?
a. somatic mutation
b. silent mutation
c. neutral mutation
d. harmful mutation
e. beneficial mutation

Explanation:

Trichromatic vision is a beneficial trait as it allows humans to distinguish between red, green, and blue colors. A mutation that enables this trait would be considered beneficial as it provides an advantage in terms of visual perception and interaction with the environment. Somatic mutations occur in non - reproductive cells and are not passed on to offspring. Silent mutations do not change the amino acid sequence of a protein. Neutral mutations have no significant effect on the organism's fitness. Harmful mutations have a negative impact on the organism. Since trichromatic vision is an advantageous trait, the mutation is beneficial.

Answer:

E. beneficial mutation
