The correct answer is - gain of function, and dominant.
Explanation:
A mutation in which the gene that altered carries out the production of the product that has a new pattern of gene expression or a new molecular function.
Function mutations are always gain by almost always Dominant or in some rare cases semi-dominant so, the mutation in a coat color gene of a mouse alters an enzyme such that it produces a red pigment instead of the wild type, which is tan. This is a gain of function mutation, which is most likely dominant.
The correct answer is - gain of function, and dominant.
