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 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.
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.
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 do homologous chromosomes do in prophase 1?
Homologous chromosomes do not pair during mitosis. they only pair in meiosis to form tetrads.

Does homologous chromosomes pair up during meiosis 1?
Yes, during prophase I.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?

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.
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 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 do homologous chromosomes do in prophase 1?
Homologous chromosomes do not pair during mitosis. they only pair in meiosis to form tetrads.
What is it called when homologous chromosomes trade alleles?
Crossing-over is when segments of homologous chromosomes switch places. This process occurs during prophase I of meiosis and results in recombinant chromosomes. This adds to the variation seen in offspring.
What results from the process of crossing over during prophase I?
During crossing-over, chromosomes of a homologous pair breaks and exchange genes.
What is the pairing of homologous chromosomes called?
The pairing of homologous chromosomes during prophase 1 is called crossing over. The chromosomes make a copy of themselves. The 4 cells can now twist together and exchange pieces.
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
