Do homologous chromosomes pair in mitosis?
No, only in meiosis
What is unique to mitosis and not a part of meiosis?
homologous chromosomes behave independently Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
How many homologous chromosomes interact with each other or dont during mitosis and meiosis?
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
In mitosis or meiosis do doubled chromosomes pair to form tetrads?
Tetrads form during meiosis. Tetrad refers to the four chromatids of homologous chromosomes.These are present during Prophase.

What are Homologous chromosomes that occurs in meiosis but not mitosis is called?
Tetrad
What is the difference between prophase mitosis and prophase meiosis?
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
How many homologous chromosomes interact with each other or dont during mitosis and meiosis?
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.

Tetrads form during meiosis. Tetrad refers to the four chromatids of homologous chromosomes.These are present during Prophase.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
Do the chromosomes separate once in both mitosis and meiosis?
No. In mitosis the chromosomes separate once. In meiosis, in anaphase I, homologous chromosomes separate, but are still attached as sister chromatids. In anaphase II, the sister chromatids separate. So there are two chromosome separations in meiosis.
What is a meiotic nondisjunction event?
Nondisjunction is when homologous chromosomes fail to separate in Meiosis I, or sister chromatids fail to separate in Meiosis II or Mitosis. This results in daughter cells with an incorrect number of chromosomes.
What are The faces of mitosis and meiosis?
there are no faces in mitosis and meiosis but there are phases
How many cells do you end up with after mitosis and meiosis?
After mitosis you have two cells and after meiosis you have 4 cells.
