Flgure A shows the color of deer mice (Peromyscus maniculatus) In the Nebraska
Sand Hills (white area) and the rest of the State (grey area). Mice are shown on
the habitat they are not nomally found on. The color of the Sand Hills Is shown
below the light-colored mouse (normal habltat), while the color of the ground in
the rest of the State is shown below the dark-colored mouse. Figure B shows the
phenotyplc difference in the hair shaft of the wild-type and the light-colored
(wideband) mice. Figure C shows the expressilon levels (MRNA) of the Agouti
alleles responsīble for the phenotype seen in figure B. a+= wild-type Agouti alele,
a-= a deletion of the Agouti allele, awb = wideband Agouti allele mutation, and
the black rectangles undermeath each bar is the relative difference in the hair
shaft band phenotype. Wder band means lighter hair color in the deer mice. b.
The Sand Hills were created by volcanic activity 15,000-8,000 years ago. How
