How do chromosomes align differently during meiosis compared to mitosis?
During meiosis, chromosomes align in pairs, with one chromosome from each parent, to exchange genetic material. This process is called crossing over. In mitosis, chromosomes align individually and do not exchange genetic material.
How is metaphase 1 different in meiosis compared to mitosis?
In metaphase 1 of meiosis, homologous chromosomes line up in pairs at the center of the cell, while in mitosis, individual chromosomes line up singly.
How do homologous chromosomes behave differently during mitosis and meiosis?
During mitosis, homologous chromosomes do not pair up and exchange genetic material, while in meiosis, homologous chromosomes pair up and undergo genetic recombination. This results in different behavior and outcomes for homologous chromosomes in the two processes.
Are homologous chromosomes present in both mitosis and meiosis?
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.

How do the results of mitosis and meiosis differ?
the amount of chromosomes in a cell. meiosis is used in sexual reproduction and mitosis is just making more cells. chromosomes in a human after meiosis=24; mitosis=48.
How is the chromosomes number halved during cell division: through mitosis or meiosis?
The chromosomes number is halved during cell division through meiosis, not mitosis.
What processes separate eukaryotic chromosomes?
Mitosis and Meiosis
How is metaphase different in mitosis and meiosis?
In both mitosis and meiosis, metaphase is the stage where chromosomes line up in the middle of the cell. However, in mitosis, the chromosomes line up in a single row, while in meiosis, they line up in pairs. This is because meiosis involves two rounds of cell division, resulting in the separation of homologous chromosomes.
How does metaphase in meiosis differ from metaphase in mitosis?
In metaphase of meiosis, homologous chromosomes line up in pairs, while in metaphase of mitosis, individual chromosomes line up singly.
What are Homologous chromosomes that occurs in meiosis but not mitosis is called?
Tetrad
What are the differences in the occurrence and significance of metaphase in mitosis compared to meiosis?
In mitosis, metaphase occurs once and is important for ensuring equal distribution of chromosomes to daughter cells. In meiosis, there are two rounds of metaphase, each crucial for creating genetic diversity through the separation of homologous chromosomes and sister chromatids.
