How slight variations are introduced in asexual reproduction? Explain in detail.

During asexual reproduction variation may be introduced due to the error during copying of DNA or mutation. As, no biochemical reaction is 100% perfect, so DNA copying or replication also produces some errors which results in the variation of the asexually reproduction organisms. Mutation is the alteration in the genetic matter due to some natural (DNA copying) or artificial factors like chemicals, x rays etc)
