Thanks to a novel recessive mutation,a certain plant species has begun to invade colder Arctic regions outside of its normal range.However,this cold-tolerant mutation has not yet become fixed in the population.A second mutation arises that promotes self-pollination.Do you predict that the self-pollination allele will be selected for in the Arctic regions? Why or why not?
A) Yes.The self-pollinated plant is more likely to maintain the cold-tolerant mutation,and plants in the Arctic are unlikely to be visited by pollinators.
B) No.Outcrossing is always beneficial,since it enhances genetic diversity.
C) No.Plants that produce flowers must be cross-pollinated for proper seed development.
D) Cannot make a prediction from the information given.It depends on whether the plant is normally insect-pollinated or wind-pollinated.
