What is the difference between mitosis and meiosis ?/

Answer»

\large{\bf{\red{\underline{\underline{Answer:}}}}}

Mitosis:-

  • Mitosis takes place in somatic cells.
  • Two daughter cell are formed.
  • A mitotic mother cell can either be happier or diploid.
  • The number of chromosomes per nucleus remains the same after division.
  • It is preceded by a S-phasein which the amount of DNA in duplicated.
  • In mitosis there is no pairing of homologous chromosomes.
  • There is no exchange of DNA between chromosomes.
  • The centreomerr split during anaphase.
  • The genotypes pf the daughter cell is identical to that of the mother cell.
  • After mitosis , each daughter cell has EXACTLY the same DNA strands.

Meiosis:-

  • Meiosis takes place in the reproductive cells of sexually REPRODUCING ORGANISMS.
  • FOUR daughter cells are formed.
  • A meiotic mother cell is diploid.
  • The meioti products contain a diploid number of chromosomes in contrasting the number of chromosomes in mother cell.
  • In meiosis only meiosis I may be preceded by a S-Phase.
  • During prophase I compete pairing of homologous chromosomes takes place.
  • There is at least one crossing over Or DNA exchange perhomogous pair of chromosomes.
  • The centromeres split during anaphase-II but not during anaphase-I
  • Meiotic products differ in their genotype from the mother cell.
  • After meiosis each daughter cell jas re combined DNA strands.
