Species B, which reproduces asexually, is likely to grow more rapidly than Species A because asexual reproduction can occur faster and does not require a mate. However, asexual reproduction also means that harmful mutations are more directly passed to offspring without the potential for genetic recombination to eliminate them, as happens in sexual reproduction. Thus, Species B is also more likely to accumulate harmful mutations over time.
