WebAsexual reproduction involves a single cell dividing to make 2 new, identical daughter cells. Mitosis & binary fission are examples of asexual reproduction. Sexual reproduction involves two cells (egg & sperm) joining to make a new cell (zygote) that is NOT identical to the original cells. Meiosis is an example. 67. fnf lights down remix
