उत्तर १
Identical twins are produced from one ovum i.e. one developing zygote splits and grows into two foetuses whereas fraternal twins are produced when two ova get fertilized at a time.
उत्तर २
Identical twins: Identical twins being produced from a single egg are either both boys or both girls, and for the same reason, they are very similar (identical) to each other. Yet, everything is not similar in identical twins; for example, fingerprints, birthmarks, and even handwriting are not similar.
Fraternal twins: Sometimes, two eggs are released from ovaries at a time, and both may get fertilised to produce two individuals. Such twins, produced from two eggs, are called fraternal twins. Fraternal twins may be either both boys or both girls or one boy and one girl.
