Two populations of cloned mice are being studied to try to characterise an unknown locus. All the mice are housed and raised identically, but one population has a single nucleotide polymorphism in the locus of interest, resulting in a non-sense mutation. The mutant mice are observed to forage more frequently but for shorter periods of time compared to those without the mutation. This locus is therefore

Question

Quizplus · Accepted Answer

The observed difference in foraging behavior between the two populations of cloned mice, based on the presence or absence of a single nucleotide polymorphism resulting in a non-sense mutation, indicates that this locus influences foraging behavior. Therefore, it acts as a genetic marker for foraging behavior.
