What happened to fur color of mice living on dark lava rocks?

I NEED HELP ASAP

They have a genetic mutation that affects their fur color. Why do dark-colored rock pocket mice on dark lava flows have white bellies? There is no selection for dark bellies by visual predators. ... Mutations for advantageous traits are more likely to be passed on to the next generation.

Explanation:

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
