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.

Homologous chromosomes pair and undergo crossing over during?
Paired homologous chromosomes are found at the spindle equator during metaphase. During metaphase the chromosomes line up on the plate and attach to the fully formed spindle.
What stage in meiosis do homologous chromosomes come together?
During meiosis, the homologous chromosomes come together during prophase I. Pairs of homologous chromosomes align during a process called synapsis and form a tetrad (four sister chromatids, two from each pair of homologous chromosomes). During synapsis, crossing over may occur, during which homologous chromosomes exchange genetic material.
Nondisjunction occurs when?
homologous chromosomes fail to separate during meiosis
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.

What is the pairing of homologous chromosomes during meiosis?
synapsis
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
When do homologous chromosomes separate into the daughter cells?
They are separated in Anaphase I of Meiosis I.
The pairing of homologous chromosomes during meiosis is called what?
synapsis

Does homologous chromosomes pair up during meiosis 1?
Yes, during prophase I.
When do homologus chromosomes occur short answer please thankss?
Homologous chromosomes occur during meiosis. Meiosis reduces the chromosome number by half.
During which phase of meiosis do spindle fibers move the sister chromitatdes to the center of cells?
That would be anaphase I of meiosis. We know the question is concerning meiosis and not mitosis because it involves homologous chromosomes. Anaphase I begins when the kinetochore fibers stemming from the centrioles "grab" the centromeres of homologous chromosomes and "pull" them towards opposite ends of the cell.The mechanisms are a little more complicated than "grabbing" and "pulling," but for this question the mechanisms are of little importance.
What action occurs during meiosis exchanging pieces of chromosomes between homologous chromosomes?
crossing over
