Detailed explanation-1: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!
Detailed explanation-2: -Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.
Detailed explanation-3: -In asexual reproduction, only a single parent is involved. So, the offspring produced are genetically identical to the parent and to each other as well. Such offspring are called clones.
Detailed explanation-4: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.
