Identical equations or Identities - Now study the equations given below: a) x + 3 + x + 4 = 2x + 7 2x + 7 = 2x + 7 (By simplification) [ \ any value given to 'x' always satisfies the equation] Similarly, b) (3a + 4) + 2 (a - 1) = 5a + 2 i.e., 5a + 2 = 5a + 2 (By simpli..

The monozygotic (identical twins) develop from a single zygote by separation of the two blastomeres after the first cleavage. Therefore, they have similar genetic traits, except for rare chances of mutation. Fraternal twins develop from different zygotes. Therefore, they are no more alike..
