In male cells, how do the two cells at the end of telophase I and cytokinesis I compare to the original cell in terms of chromosome number?

• A. They have double the number of chromosomes as the original cell.
• B. They have half the number of chromosomes as the original cell.
• C. They have the same number of chromosomes as the original cell.
• D. They have one-quarter the number of chromosomes as the original cell.

Answer: (B)

Verified step by step guidance

1. Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells from one diploid cell.
2. Recognize that meiosis consists of two stages: Meiosis I and Meiosis II. Telophase I and cytokinesis I occur at the end of Meiosis I.
3. During Meiosis I, homologous chromosomes are separated, which means that each resulting cell receives one chromosome from each homologous pair.
4. In a diploid cell, chromosomes are present in pairs. After Meiosis I, the two resulting cells have half the number of chromosomes compared to the original diploid cell.
5. Conclude that at the end of telophase I and cytokinesis I, each of the two cells has half the number of chromosomes as the original cell, making them haploid.
