A species 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?

(a) - There will be less genetic variation from recombination and a risk of not adapting quickly to environmental change.

(b) - The species will increase in numbers because genetic variation is increased.

(c) - There will be fewer deaths from natural selection because sexual recombination always leads to extinction.

(d) - There will be more deaths from natural selection because there is no mutation.

(e) - The species will compensate for loss of genetic variation by hybridizing with other species.

A) There will be less genetic variation from recombination of risk of not adapting quickly to environmental changes

Explanation:

Natural selection: It is the process of adapting a species by a natural selection in the environment by the selection to change in re productivity in geno-type. It is processed in which the genes are selected and preserved for the future. These genes are those which survival chances are more and this selection of generation to generation has been multiplied. The genetic frequency the same generation to generation. The mutation is another that leads to a change in the generation that takes a population and occurs at a very low cost.
