Assertion (A) : Meiosis is known as reductional division.
Reason (R) : Because the number of chromosomes is reduced to half during meiosis.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is NOT the correct explanation of A.
A is true but R is false.
A is false but R is true.
Answers (1)
Because the number of chromosomes is decreased to half during meiosis, the process is known as reductional division. This happens as a result of meiosis, which involves two rounds of cell division and yields four haploid daughter cells with half as many chromosomes as the parent cell. Homologous chromosomes couple up and exchange genetic material through a process known as crossing over during the first meiotic division (meiosis I). Following the separation of the homologous chromosomes, two haploid daughter cells with a single set of chromosomes are created. The sister chromatids of each chromosome split during the second meiotic division (meiosis II), which produces four haploid daughter cells. Hence option 1 is correct.
Option "1 is true but R is false" is incorrect because both statements are true.
Option "1 is false but R is true" is incorrect because the assertion is true, and R is an explanation of A.
Option "Both A and R are true but R is NOT the correct explanation of A" is incorrect because the reason (R) is the correct explanation of the assertion (A).
