Bot reword this as an 8th grader: Asexual reproduction does not use the fusion of gametes or change in the number of chromosomes. The offspring that come from asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent. So asexual reproduction is more beneficial.

In asexual reproduction, there's no mixing of gametes or chromosome changes. The offspring inherit genes from just one parent, whether it's a single cell or a multicellular organism. That's why asexual reproduction is considered more advantageous.
