What is the process in which homologous pairs of chromosomes separate and move apart is known as?
The process which you are talking about is "Meiosis"... Actually, this process is carried out in gamete producing cells like sperms and eggs. Meiosis process is divided into two parts: Meiosis I and Meiosis II.
Meiosis I has four phases: Prophase I, Metaphase I, Anaphase I nad Telophase I.
During Anaphase I of Meiosis I of Meiosis cell division, homologous pairs of chromosomes are separated and stretched toward opposite poles of the cell with the help of Microtubules organelle of the cell.
What else can I help you with?
Which phase do homologous chromosomes separate?
Anaphase I, and then again in Anaphase II--two seperations occur in meiosis.
During what in meiosis the chromosomes move apart to the opposite poles of the cell?
The process described in your question is called anaphase. One can remember this step of the cell cycle easily because the chromosomes form 'A' shapes at the ends of the poles- and 'A' is of course the first letter of anaphase. The next step in the cell cycle is telophase- where the cell undergoes cytokinesis- splitting to form two new cells.
How many times do chromosomes separate in the process of mitosis?
Chromosomes separate once in mitosis. This occurs during the anaphase stage, where the sister chromatids are pulled apart and move towards opposite poles of the cell.
What is spindle fibers pull the sister chromatids apart?
During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes. The spindle fibers are composed of micro-tubules. The spindle fibers continue to shorten during anaphase in order to bring the chromosomes at two poles.During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes.

What is the role of the spindle fibers during mitosis?
They pull the sister chromatids apart.
Which phase do homologous chromosomes separate?
Anaphase I, and then again in Anaphase II--two seperations occur in meiosis.
When do allele pairs separate?
Allele pairs separate during the process of meiosis, specifically during the anaphase I stage. This is when homologous chromosomes are pulled apart, causing the alleles to separate and end up in different daughter cells.
Do the individual chromosomes move apart in mitosis or meiosis?
Yes, in both mitosis and meiosis, the individual chromosomes move apart during cell division. In mitosis, the sister chromatids of each chromosome separate and move to opposite poles of the cell, while in meiosis, homologous chromosomes separate in the first division and sister chromatids separate in the second division.
Which phase pulls spindle fibers apart from homologous chromosomes?
Anaphase
In which phase did crossing over get broken apart so the original homologous chromosomes exchange pieces with each other?
Crossing over occurs during prophase I of meiosis, where homologous chromosomes pair up and exchange genetic material. This process involves the formation of structures called chiasmata, where the chromosomes physically break and rejoin, leading to genetic recombination. Once the exchange is complete, the homologous chromosomes are separated in the subsequent phases of meiosis.
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.

Chromosomes separate once in mitosis. This occurs during the anaphase stage, where the sister chromatids are pulled apart and move towards opposite poles of the cell.
When do the tetrads get pulled apart in meosis?
In meiosis, the tetrads (group of four chromatids) get pulled apart during anaphase I. This is when homologous chromosomes separate and move to opposite poles of the cell, resulting in the reduction of chromosome number from diploid to haploid.
What is spindle fibers pull the sister chromatids apart?
During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes. The spindle fibers are composed of micro-tubules. The spindle fibers continue to shorten during anaphase in order to bring the chromosomes at two poles.During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes.

What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
