The figure shows three mouse populations and their associated changes in the frequency of B,the allele for dark fur.The recessive b allele codes for white fur.After 20 generations,in which population would you be most likely to encounter a white mouse? A)N₁ B)N₂ C)N₃ D)There is an equal probability of encountering a white mouse in all three populations. E)There is an equal probability of encountering a white mouse in populations N₁ and N₃ and this is higher than in N₂.
