#Bio-Informatics
  1. It cannot identify insertions or deletions within aligned regions.
  2. It assumes that all sequence similarities are the result of random chance.
  3. It may fail to detect shared ancestry if sequences have diverged too significantly over time.
  4. It is only effective for sequences that share 100% identity.

Q. Consider the following statements regarding cytoplasm transfer via somatic hybridization:
Statement I: Cytoplasm transfer that normally takes 6–7 years via backcrossing can be achieved in just one year using protoplast fusion.
Statement II: Iodoacetate is used to inactivate the nucleus of the recipient parent protoplasts.
Statement III: Irradiation of donor protoplasts is used to inactivate their nuclei.
Statement IV: The resulting cybrids contain the nucleus of parent A and mitochondria of parent B.
