Question: Where do the chromosome pairs line up in meiosis?

At the end of prometaphase I, meiotic cells enter metaphase I. Here, in sharp contrast to mitosis, pairs of homologous chromosomes line up opposite each other on the metaphase plate, with the kinetochores on sister chromatids facing the same pole. Pairs of sex chromosomes also align on the metaphase plate.

Where do chromosomes line up in meiosis?

Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

Why does meiosis have 2 divisions?

From Amy: Q1 = Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.

What is the chromosome number of daughter cells in meiosis?

Now there are two daughter cells, each with 23 chromosomes (23 pairs of chromatids). In each of the two daughter cells the chromosomes condense again into visible X-shaped structures that can be easily seen under a microscope.

What is the chromosome number of daughter cells in mitosis?

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.

What happens between meiosis I and meiosis II that reduces the number of chromosomes?

In meiosis I homologous pairs align and are separated reducing the number of chromosomes by half. In meiosis II the dyads align and sister chromatids are separated.
