Question
- a mutation in the taqpep gene affects how pigment is distributed throughout a cheetahs coat. what role does this mutation play in trait variation?
it creates a different protein that leads to a new spot pattern.
it removes all genetic variation from the population.
it allows the cheetah to camouflage in any environment.
it prevents the cheetah from forming any spots.

Analyze the effect of gene mutations on proteins
A mutation in a gene alters its DNA sequence, which can lead to the production of a modified protein with a different structure or function.
Connect protein changes to phenotypic traits
The altered protein affects cellular processes, in this case, how pigment is distributed, resulting in a visible variation in the cheetah's coat pattern (phenotype).
Evaluate the given multiple-choice options
- Option 1 correctly describes this biological pathway: a mutation creates a different protein, leading to a new spot pattern.
- Option 2 is incorrect because mutations introduce, rather than remove, genetic variation.
- Option 3 is incorrect as a single coat pattern mutation does not grant universal camouflage.
- Option 4 is incorrect because the mutation alters pigment distribution (such as blotches instead of spots) rather than preventing all spot formation.
