What is the key difference in genetic outcome between sexual and asexual reproduction?

The key difference in the genetic outcome between sexual and asexual reproduction is that asexual reproduction produces genetically identical offspring. This process occurs without the fusion of gametes, as seen in organisms such as bacteria, where a single organism divides to create clones of itself. These clones carry the same genetic material, leading to low genetic diversity among the offspring.

In contrast, sexual reproduction involves the combination of genetic material from two parents through the process of gamete fusion, resulting in offspring that have a mix of characteristics from both parents. This blending of genetic material contributes to greater genetic diversity within a population, which can enhance adaptability and survival.

The other options presented misrepresent the nature of these reproductive strategies, which is why they do not correctly convey the fundamental distinction in genetic outcomes.
