Question

In meiosis chromosome number becomes

• A. half of as parernt chromosome
• B. same as that of parent chromosome
• C. one fourth of its parent chromosome
• D. none of the above

Answer 1

Answer: (A)

half of as parernt chromosome

Answer 2

Meiosis is the type of cell division in which a parent cell gives rise to four daughter cells, which are having half the chromosome number as compared to the parent cell. The process by which reduction in chromosome number takes place is called reduction division or first meiotic division or heterotypic division. $\underset{\text{diploid}}{\text{Parent cell}(2n)} {->[\text{Meiosis} I]} \underset{\text{haploid}}{2 \,\text {cells}(n)}$ The second meiotic division is the homotypic or equational division. $2$ cell $(n) {->[\text{Meiosis} II]} \underset{\text{haploid}}{4 \,\text {cells}(n)}$ Ultimately four daughter cells are produced that have half the chromosome number of their parents.
