N the lab, Nachman examined dark mice from two different populations living hundreds of miles apart. The mice looked nearly identical. Their dark color was caused by two different genes. What does this tell you?
a. dark color evolved only once in rock pocket mice
b. under very similar conditions, natural selection can favor very similar adaptations
c. there are at least two genes involved in creating dark mouse fur
d. two completely different mutations in two separate genes can generate the same phenotype
e. dark fur color evolved independently on each lava flow

Answer is Option "b,c,d & e"

Explanation:

Several conclusions can be drawn from this observation:The adaptation for fur color in the mice from both locations was similar, this could be because both environments have almost similar conditionsIt is also an indication that the dark fur color may have evolved independently in both populationsTwo completely different mutations in two separate genes can generate the same phenotype. The mice looked nearly identical because of the fur color and other characteristics of the mice which cause by two different genesHence, the right answer is option "b,c,d & e"
