What can be a negative effect of asexual reproduction?

Answer 1

A negative effect of asexual reproduction is the lack of genetic diversity, which can make populations more susceptible to diseases and environmental changes. Without genetic variation, all offspring are clones of the parent, potentially leading to a uniform response to threats. This can hinder a population's ability to adapt and survive in changing conditions, increasing the risk of extinction. Additionally, if a harmful mutation occurs, it can be passed on to all descendants, compounding the issue.
