Vedclass · Answer

(C) Meiosis is a specialized type of cell division that reduces the chromosome number by half,resulting in the production of haploid gametes.When these haploid gametes fuse during fertilization,the diploid number of chromosomes is restored in the zygote.Therefore,meiosis is essential for maintaining the constant number of chromosomes in a sexually reproducing species across generations.Option $A$ is incorrect because meiosis produces cells with half the number of chromosomes.Option $B$ is incorrect because meiosis occurs only in germ cells,not all body cells.Option $D$ is incorrect because organ development occurs through mitosis.
