When we plant potato tubers of the previous year, the potatoes we later harvest are just as nutritious and tasty. This is because there was no new combination of hereditary information, with one plant being pollinated with the DNA of another. They are in fact clones of the previous year's plant. Strawberries are also propagated from runners which are actually clones of the parent plant, bearing fruit with the same colour and taste. We also see cloning in the animal kingdom.
Aphids can reproduce both sexually and by cloning.
In spring the first aphid generation hatches out of fertilised eggs. Later, the aphid lays eggs that start to divide without being fertilised. They are clones of the mother. Concerning people, we know that identical twins are real clones. The fertilized egg splits in two, and each of these two 'daughter' cells develops separately.
