In the lab, dr. nachman examined dark-colored mice from two different populations living hundreds of miles apart. the mice looked nearly identical. however, their dark color was caused by two different genes. from this, one can conclude all of the following except:
a) two completely different mutations in two separate genes can generate the same phenotype.
b) dark fur color evolved independently on each lava flow
c) there are at least two genes involved in creating dark mouse fur under very similar conditions, natural selection can favor very similar adaptations.
d) dark color evolved only once in rock pocket mice pearsorn
