Question

Which division maintains genetic similarity?
A.Mitosis
B.Meiosis
C.Amitosis
D.Reduction division

Answer 1

Hint: The series of events by the process in which a cell duplicates its genome, synthesizes other constituents of the cell and eventually divides into two daughter cells is termed as cell cycle. It is a controlled genetically through sequence of changes that occur in a newly formed cell by which it duplicates its contents, undergoes growth and division to form two daughter cells.

Complete answer:
When a cell enters the cell cycle, it undergoes through different phases which prepare it for cell division. Synthesis of DNA, duplication of cell organelles, synthesis of various proteins are the different needs of a cell which is about to enter mitosis. The cell secretes these constituents in a sequential pattern to make sure that proper division and distribution of components occurs within the two daughter cells. This makes sure that a proper intact genome enters the two daughter cells and progenies developed are functionally and structurally intact. The daughter cells then develop and again at maturity undergo cell division.

Now let us find solution from given options:
A. Mitosis: It is Also termed as equational division. When this division occurs, the number of chromosomes remains the same that is in the parent and the offspring generation, so it helps to maintain the genetic similarity across the parents and offspring.
B. Meiosis: Meiosis is The double division in which the Diploid cell forms 4 haploid cells and each cell poses half the number of chromosomes, so it does not maintain the genetic equality among the parents and offspring.
C. Amitosis: It is a kind of asexual reproduction that usually takes place in acellular organisms like that of bacteria and it is also said as direct cell division.
D. Reduction division: It is also called as Meiosis. Meiosis is the double division in which the Diploid cell forms 4 haploid cells and each cell poses half the number of chromosomes, so it does not maintain the genetic equality among the parents and offspring.

Hence, the correct answer is option (A)

Note: Mitosis is defined as a process in which a parent cell gets divided into two similar daughter cells. These cells are similar and identical to each other and also to parent cells. It is also termed as equational division because two daughter cells possess exactly the same number of chromosomes as that present in the parent cell.
