Dark-colored mice from two different populations living hundreds of miles apart were examined and the mice looked nearly identical. The dark color fur in the two different populations of mice was caused by two different genes. What does
this tell you? (Note: More than one answer is correct.)
Dark color fur evolved only once in rock pocket mice
Under similar conditions, natural selection can favor similar adaptations
Different mutations in two different genes cannot generate the same phenotype
There are at least two genes involved in creating dark-colored mouse fur
Dark fur color evolved independently on each lava flow

Refer to this portion of a dichotomous key for fish identification to answer the question. 1. (a) has a single dorsal fin ® 5 (b) has a double dorsal fin ® 2 2. (a) one fin is spiny, the other is smooth ® 3 (b) one fin is not spiny or smooth ® 4 5. (a) has small fin on back near tail ® 6 (b) has no fin on back near tail ® 7 6. (a) has barbs near the mouth ® catfish (b) does not have barbs near the mouth ® 10 7. (a) tail is asymmetrical ® 8 (b) tail is symmetrical ® 9 10. (a) scales are small ® trout (b) scales are large ® whitefish what is the next step to complete to identify a fish that has a single dorsal fin, no fin on the back near the tail, and no barbs near the mouth? step 2 step 5 step 7 step 10
