AIIMS 2018 Botany Meiosis MCQ Question
Assertion: Meiotic division results in the production of haploid cells.
Reason : Synapsis occurs during zygotene of meiosis.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Meiosis is a specialized form of cell division that reduces the chromosome number from diploid (2n) to haploid (n) through two rounds of division, involving synapsis where homologous chromosomes pair up to form bivalents. Each bivalent consists of four chromatids, as each chromosome is replicated into two sister chromatids prior to meiosis. The other options may contain inaccuracies regarding the process of meiosis or the structure of chromosomes, such as misrepresenting the number of chromatids or the stages of meiosis involved in haploid cell formation. Understanding these concepts is crucial for grasping the mechanisms of genetic diversity and reproduction in organisms.
