Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is <u>better adapted to a changing environment and promotes the faster </u><u>evolution </u><u>of a </u><u>species</u><u>.</u>
The main benefit of sexual reproduction is that it allows for a<u> </u><u>greater diversity </u><u>of the </u><u>species</u><u> which enhances the probability of </u><u>survival</u><u>.</u> This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (<em>the ability of a member of the species to choose a spouse with desirable traits</em>) <u>leads to </u><u>offspring </u><u>who over time are increasingly better </u><u>adapted </u><u>to life in the given </u><u>environment</u><u>, with specific traits tailored for </u><u>survival</u><u>.</u>
