Solution:Offspring produced by asexual reproduction are genetically similar to their parents and are called clones. Asexual reproduction involves DNA copying from a single parent.In sexual reproduction, DNA copying from both male and female parents occurs. Sexual reproduction also results in the formation of new species, and this leads to the process of evolution.


Sexual reproduction

Sexual reproduction is the method of reproduction in which a female gamete (egg cell) and a male gamete (sperm cell) fuse to form a zygote. Female gametes and male gametes are haploid cells, and they join together to form a diploid zygote.Sexually produced progenies are not identical to their parents.This method of reproduction also increases genetic variation and leads to evolution.Different types of sexual reproduction involves conjugation and syngamy.

Examples:Human,Dog,Chimpanzee,Lion

Asexual reproduction

Asexual reproduction is the method of reproduction that does not involve the combination of gametes, and all the progenies formed by asexual reproduction are genetically similar to their parents and are called clones. This process does not result in variations and does not result in evolution. Different types of asexual reproduction involve budding, binary fission, fragmentation, apomixis, parthenogenesis, vegetative reproduction etc.

 Examples: amoeba, hydra, yeast, planaria
