Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells, each with half the number of chromosomes of the parent cell.
Recall that meiosis consists of two stages: Meiosis I and Meiosis II. Each stage has its own phases: prophase, metaphase, anaphase, and telophase.
In Meiosis I, homologous chromosomes are separated. By the end of telophase I, two cells are formed, each containing one set of chromosomes.
Each chromosome at the end of telophase I still consists of two sister chromatids because the centromeres have not yet divided. This is a key point to remember.
Therefore, at the end of telophase I, each chromosome in the two newly formed cells consists of two chromatids.
