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.

Which stage of meiosis do homologous chromosomes line up in the center of the cell?
metaphase i think
What homologous pairs of chromosomes line up in the middle of the spindle during meiosis name the phase one or two?
During Metaphase 1 the homologous pairs of chromosomes line up at the center of the cell. They arrange around the spindle during meiosis.
What is the prophase 1?
Prophase I is the stage in meiosis in which homologous chromosomes pair up. During this time, chromatids from the homologous pairs cross over and exchange segments with one another.
Which is the process during meiotic cell division where there is a separation of homologous pairs of chromosomes?
Homologous chromosomes are chromosomes that carry genes that perform the same functions. Seperation of these chromosomes occurs during Mitosis where sister chromatids will be separated and pulled to opposite sides of a dividing cell. It also occurs during Meiosis 1 and 2 where in meiosis homologous chromosome pairs will line for the first time on the metaphase plate and be pulled to opposite sides of the cell and once again (without duplicating again) line up on the metaphase plate and be pulled to opposite ends of the cell. So the separation of homologous chromosomes happens in Meiosis stage 1 where you have a diploid organism with 4 copies of its chromatids and these homologous chromosomes (chromatids connected by a centromere) are pulled to opposite ends of the cell.
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.
Which stage of meiosis do homologous chromosomes line up in the center of the cell?
metaphase i think
What is the separation of homologous pairs of double chromosomes during meiosis?
the stage is called the "first division"
What specific stage in meiosis do homologous chromosomes separate?
Anaphase lAnaphase I
The process where replicated homologous chromosomes are linked to form tetrads is called?
Meiosis Stage II.
Meiosis leads to variation in offspring by what?
In prophase of meiosis, first, a stage comes (known as crossing over) in which homologous chromosomes, after pairing, exchagne their genetic material. This is the stage where varition occurs during, and only in, meiosis I.
Homologous chromosomes segregate towards opposite poles of a dividing cell during which stage?
meiosis I
What homologous pairs of chromosomes line up in the middle of the spindle during meiosis name the phase one or two?
During Metaphase 1 the homologous pairs of chromosomes line up at the center of the cell. They arrange around the spindle during meiosis.
What is the prophase 1?
Prophase I is the stage in meiosis in which homologous chromosomes pair up. During this time, chromatids from the homologous pairs cross over and exchange segments with one another.
Main stage of meiosis?
The main stage of meiosis is called the "reduction division" or "meiosis I." During this stage, homologous chromosomes pair up and exchange genetic information through a process called crossing over. They then separate, resulting in two cells with half the number of chromosomes as the original cell. Meiosis II then follows, where sister chromatids separate, resulting in four non-identical daughter cells.
Is duplication of paired chromosomes in the first stage of meiosis?
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
How is mitosis different from mitosis?
During meiosis there is pairing between homologous chromosomes for exchange of chromatin material by crossing over and these chromosomes get separated in first stage of meiotic division, thus half of the chromosomes separate at each pole; the second stage of meiosis is more or less similar to mitotic division. At the end of meiosis 4 daughter nuclei are formed whereas in mitosis only 2 daughter nuclei are formed without reduction in the number of chromosomes.
Which is the process during meiotic cell division where there is a separation of homologous pairs of chromosomes?
Homologous chromosomes are chromosomes that carry genes that perform the same functions. Seperation of these chromosomes occurs during Mitosis where sister chromatids will be separated and pulled to opposite sides of a dividing cell.
