How does a lack of genetic diversity in asexual reproduction make populations vulnerable

to diseases or environmental changes? (5 sentences) short

1 answer

Asexual reproduction leads to the production of genetically identical offspring, resulting in low genetic diversity within a population. This uniformity means that all individuals share the same genetic vulnerabilities, making them equally susceptible to diseases and environmental changes. When a pathogen or a harmful environmental shift occurs, the entire population may be affected simultaneously, leading to significant declines or extinction. In contrast, genetically diverse populations can have individuals with varying traits that may provide resistance or adaptability. Ultimately, the lack of genetic diversity limits the ability of asexual populations to respond to challenges, increasing their vulnerability.
