Answer:
The answer is D
Explanation:
Answer:
The process by which diploid cells undergo and produce haploid gametes is called meiosis.
1. Meiosis is a type of cell division that occurs in the reproductive cells, also known as germ cells.
2. The primary purpose of meiosis is to reduce the chromosome number in half, resulting in the formation of haploid cells.
3. Diploid cells contain two sets of chromosomes, one from each parent, while haploid cells contain only one set of chromosomes.
4. Meiosis consists of two rounds of division, known as meiosis I and meiosis II.
5. During meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing over.
6. This genetic exchange promotes genetic diversity and creates new combinations of genes.
7. After crossing over, the homologous chromosomes separate, resulting in two haploid cells with duplicated chromosomes.
8. Meiosis II is similar to mitosis, where the duplicated chromosomes line up and separate, producing four haploid cells.
9. These four haploid cells are the gametes, such as sperm or egg cells, which are used in sexual reproduction.
10. When two gametes fuse during fertilization, the resulting zygote will have the full diploid chromosome number again.
Overall, meiosis allows for genetic variation and ensures the production of haploid gametes necessary for sexual reproduction.
