Homologous chromosomes do not pair during mitosis. they only pair in meiosis to form tetrads.

What would happen if homologous chromosomes did not pair in prophase 1?
if homologous chromosomes didn't pair up in Prophase 1 the DNA between the parents isn't distributed equally to the offspring, or variation would not occur.
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.
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.
The process of cell division that creates genetic variety in cells is what?
Genetic variation occurs due to crossing over at prophase 1 and independent assortment of homologous chromosomes at metaphase 1. Both prophase 1 and metaphase 1 are stages of meiosis 1, in which homologous chromosomes are separated.
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.
Two pairs of homologous chromosomes in prophase 1?
one
What would happen if homologous chromosomes did not pair in prophase 1?
if homologous chromosomes didn't pair up in Prophase 1 the DNA between the parents isn't distributed equally to the offspring, or variation would not occur.
Does homologous chromosomes pair up during meiosis 1?
Yes, during prophase I.
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.
What will happen to the cell as it undergoes prophase 1?
In prophase I the homologous chromosomes pair and form tetrads, during which crossing over occurs and genetic material is exchanged between the homologous chromosomes. Refer to the related link for an animated illustration.
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.
How does non-disjunction occur?
Nondisjuction occurs when the homologous chromosomes fail to separate.
The process of cell division that creates genetic variety in cells is what?
Genetic variation occurs due to crossing over at prophase 1 and independent assortment of homologous chromosomes at metaphase 1. Both prophase 1 and metaphase 1 are stages of meiosis 1, in which homologous chromosomes are separated.
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 does tetrad form in prophase I of meiosis?
In prophase I, doubled homologous chromosomes group together to form a tetrad.
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.
What phase of meiosis do homologous chromosomes cross over?
Crossing over begins early in prophase I of meiosis. At the time, homologous chromosomes Are paired along their lengths. Each gene on one homologue ia alined precisely with the corresponding gene on the other homologue. Source: my science book copy right 2006
