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 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.
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 do homologous chromosomes do in prophase 1?
Homologous chromosomes do not pair during mitosis. they only pair in meiosis to form tetrads.
What exchange of genetic material between arms of homologous chromosomes?
When chromosomes cross over. (Chromal Crossover, I believe)
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.
When Homologous chromosomes swap genetic information as part of meiosis?
Prophase I is the phase of meiosis.
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
How does tetrad form in prophase I of meiosis?
In prophase I, doubled homologous chromosomes group together to form a tetrad.
Does homologous chromosomes pair up during meiosis 1?
Yes, during prophase I.
When homologous chromosomes swap pieces during meiosis this is called?
crossing over.

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 in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
The process of cell division that creates genetic variety in cells is what?
