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 is unique to mitosis and not a part of meiosis?
homologous chromosomes behave independently Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
What 3 things homologous chromosomes have in common?
Homologous chromosome have gene of same character.
What are the matching pairs of chromosomes in the diploid cell called?
They are called homologous chromosomes (but can also be referred to as homologues or homologs).
What best describes chromosomes that contain genes for the same characteristics?
Chromosomes that have the same sequence of genes are called homologous chromosomes.
What are the chromosomes that are paired one from each parent called?
they are called homologous chromosomes
The pairing of homologous chromosomes during meiosis is called what?
synapsis
What is the pairing of homologous chromosomes during meiosis?
synapsis
What happens to each pair of duplicated homologous chromosomes during meiosis 1?
pairing of homologous chromosomes and recombination of genetic material takes place
What is meant by synapsis?
A synapsis is the pairing of 2 homologous chromosomes.
How do the chromosomes line up in meiosis1?
In meiosis 1 homologous chromosomes line up for pairing

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 in meosis 1 that does not occur in meosis 2?
Pairing between homologous chromosomes
