In populations where some species reproduce both sexually and asexually, what is expected to prevail?

In scenarios where some species have the capability to reproduce both sexually and asexually, asexual reproduction is often expected to dominate due to its numerous advantages. Asexual reproduction allows for a faster population increase because it typically involves fewer energy resources. Individuals can reproduce without the need for a mate, which eliminates the time and energy spent in finding a partner and courting behaviors.

Additionally, when conditions are stable and favorable, asexual reproduction can lead to a rapid expansion of the population by producing genetically identical offspring that are well-suited to their environment. This reproductive strategy can be particularly advantageous in environments where resources are abundant and competition is low, allowing the species to quickly capitalize on available resources.

In contrast, sexual reproduction, while beneficial for introducing genetic diversity and adaptability to changing environments over time, may not provide the same immediate population growth benefits in stable conditions. Therefore, in many cases, when both modes of reproduction are possible, asexual reproduction tends to dominate, especially in contexts where maintaining a stable and growing population is advantageous.
