Ken and Kendra share 50% of their genes. Lara an Lonnie share 100% of their genes.
The fraternal twins are just siblings that share the same womb. Each of them starts it's development as separate egg that is fertilized by a separate sperm, so they are no more similar than the other siblings.
The biological (identical) twins, on the other hand, come from the same fertilized egg, thus they share the same genes.

.Propagating a plant by cuttings will allow you to keep the special characteristics of that plant. Plants grown from seed will often be different from the parent plant and from each other. Propagating a new plant via cuttings avoids the difficulties of propagating by seed.
Disadvantages of propagating stem cuttings are: You will get a lack of genetic diversity and you may potentially increase Insect and Disease weakness in the new plant.
