Do homologous chromosomes pair in mitosis?
No, only in meiosis
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
What do homologous chromosomes do in prophase 1?
Homologous chromosomes do not pair during mitosis. they only pair in meiosis to form tetrads.
After meiosis I each daughter cell contains Please explain why one chromosome of each homolog is incorrect I added my reasoning to the answer this question?
Homologous chromosomes (also called homologs or homologues) are chromosome pairs of approximately the same length, centromere position, staining pattern, with genes for the same characteristics at corresponding loci. In meiosis I, the chromosomes are duplicated first then the homologous pairs separate together. Sections of the DNA can sometimes cross over between homologous pairs. Later, during Meiosis II, these pairs are separated into the gametes with only one of each pair. If you said there was only one chromosome, you are thinking of the final result of meiosis.
How many homologous pairs of chromosomes does a diploid human cell have?
A human gamete does not have any pairs of homologous chromosomes. A single human gamete contains 23 chromosomes, or a half set. None of these chromosomes are homologous with each other.
Do homologous chromosomes pair in mitosis?
No, only in meiosis
Is homologous chromosomes only present in cells that undergo meiosis?
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
The net result of meiosis is to reduce the number of chromosomes in gametes to only one from each?
homologous
How do differ chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.

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.
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.

A human gamete does not have any pairs of homologous chromosomes. A single human gamete contains 23 chromosomes, or a half set. None of these chromosomes are homologous with each other.
How is anaphase I of meiosis different than anaphase of mitosis?
In anaphase for both types of cell division, the centromeres of each chromosome separates and the spindle fibers pull apart the sister chromosomes. In mitosis, this is the shortest phase of cell division.However, the differences between mitosis and meiosis are different. Because meiosis is when chromosomes are "mixed and matched" in order to make new different combinations, the strands are only mixed up so when they split, they have new genes at their ends. Because mitosis is when chromosomes are duplicated, or cloned, and are copies of each other, when they split, the new cell is the exact same copy as the original.
