Question

review the passage about the effects of the mcr1 gene mutation.
a jaguar with a solid black coat (left) and a jaguar with a spotted coat
the hairs in a jaguar’s coat are colored by molecules called pigments. the pigments are made in cells at the base of each hair. when these cells make light pigments, the hair is light - colored. when these cells make dark pigments, the hair is black.
a protein called mcr1 controls how the jaguar’s cells color each hair with light and dark pigments. the function of the mcr1 protein results in jaguars with spotted coats, made up of both light - colored and black hairs. the mcr1 protein is encoded by the mcr1 gene.
a certain jaguar had a solid black coat because of a mutation in its mcr1 gene. compared to the mcr1 gene without a mutation, the mutated mcr1 gene encoded a form of the mcr1 protein with a different structure.
this different form of the mcr1 protein allowed only dark pigments to color the hairs.

Explanation:

The passage states that the MCR1 gene encodes the MCR1 protein. A mutation in the MCR1 gene affected the structure of the MCR1 protein. This change in the protein's structure then affected its function. The function of the MCR1 protein (which is controlled by its structure) relates to the color of a jaguar's coat (a jaguar trait). So, the mutation in the MCR1 gene affected the structure and function of the MCR1 protein, which in turn affected a jaguar trait (coat color).

Answer:

The mutation in the MCR1 gene affected the structure and function of the MCR1 protein in a way that affected a jaguar trait.
