Asexual Reproduction

Asexual Reproduction

Asexual Reproduction. What is asexual reproduction ?. Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only, it is reproduction which does not involve meiosis , ploidy reduction, or fertilization.
