The image shows the changes in allele frequencies in three generations of mice, when the selective pressure of predation is acting on the variation in fur color. Which
of these best explains what
happened to the allele for dark fur?
A it stayed the same because both colors could equally camouflage)
B it increased because more dark mice survived predation)
C it increased because more-dark mice passed on their genes)
