What are correct statements about meiosis?
▶️ Answer/Explanation
Ans: D
Meiosis is a specialized cell division that produces genetically unique haploid gametes through two key mechanisms: crossing over during prophase I and independent assortment of chromosomes during metaphase I. This genetic recombination ensures offspring variation, making the first statement false.
The second statement is also false because tissue repair is accomplished through mitosis, not meiosis. Mitosis produces genetically identical diploid cells for growth and repair, while meiosis is exclusively for sexual reproduction.
Therefore, the correct answer is D (No, no), as meiosis neither produces identical cells nor contributes to tissue regeneration. The diagram shows the reduction from diploid to haploid cells, confirming these fundamental differences from mitosis.
Which statements about meiosis are correct?
▶️ Answer/Explanation
Ans: C
Meiosis involves two divisions (Meiosis I and II), reducing the chromosome number by half to produce haploid gametes. The diagram likely highlights key features like crossing over (genetic variation) and independent assortment of homologous chromosomes.
Option C correctly identifies these critical aspects, while other options may misrepresent stages or outcomes of meiosis. The image confirms processes unique to meiosis, distinguishing it from mitosis.
