Which population characteristic is affected by asexual reproduction?

Asexual reproduction results in offspring that are genetic clones of the parent organism. This mode of reproduction does not involve the exchange of genetic material and, therefore, does not promote genetic diversity among the offspring. As a consequence, populations that reproduce asexually tend to exhibit genetic uniformity, meaning that the individuals in the population have very similar, if not identical, genetic makeups. This characteristic can influence how populations respond to environmental changes and diseases, as a lack of genetic diversity may limit adaptability and resilience.

In contrast to genetic uniformity, increased genetic diversity, a stable and diverse gene pool, and enhanced adaptability are typically associated with sexual reproduction, where recombination and the mixing of genetic material lead to varied offspring. Thus, the key impact of asexual reproduction on population characteristics is the promotion of genetic uniformity among individuals in the population.
