Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.

Which is an accurate comparison of the bases found in bears and the bases found in raccoons
