The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is A. 23<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

In a diploid organism, the total number of chromosomes in somatic (body) cells is represented by the symbol 2n, where “n” is the number of chromosomes in a gamete (sex cell). For a diploid organism with 46 chromosomes, the diploid number (2n) is 46. Therefore, each somatic cell contains 46 chromosomes, organized in 23 pairs.<\/p>\n\n\n\n

Gametes<\/strong> are the reproductive cells, namely sperm and egg cells in animals, and pollen and ovules in plants. These cells are haploid<\/strong>, meaning they contain only one set of chromosomes, or half the number of chromosomes found in somatic cells. The term “haploid” is represented by the symbol “n.”<\/p>\n\n\n\n

When an organism has a diploid chromosome number of 46, this means it has 23 pairs of chromosomes, making the haploid number (n) 23. Therefore, each gamete will contain 23 chromosomes, which is half of the diploid number.<\/p>\n\n\n\n

The process that produces gametes is called meiosis<\/strong>, which reduces the chromosome number by half. During meiosis, a diploid cell undergoes two rounds of division but only one round of DNA replication, resulting in four haploid cells, each with 23 chromosomes.<\/p>\n\n\n\n

When fertilization occurs, the fusion of two haploid gametes (one from each parent) restores the diploid number in the zygote, ensuring that the resulting organism has the correct number of chromosomes. In this case, the zygote will again have 46 chromosomes, maintaining the species’ chromosome number through successive generations.<\/p>\n\n\n\n

Thus, for a diploid organism with 46 chromosomes, the gametes will each have 23 chromosomes.<\/p>\n","protected":false},"excerpt":{"rendered":"
