When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, "crossing over" occurs.

What is the process where parts of two homologous chromosomes switch places?
The process where parts of two homologous chromosomes switch places is called genetic recombination. This process can occur during meiosis when homologous chromosomes pair up and exchange segments of DNA, leading to genetic diversity in offspring.
Can two different chromosomes crossover?
No, crossover events during meiosis only occur between homologous chromosomes, which are pairs of chromosomes with similar genetic information. Each chromosome crossover involves the exchange of genetic material between these homologous chromosomes, contributing to genetic diversity in offspring.
When are tetrads visible?
Tetrads are visible during prophase I of meiosis, which is the stage where homologous chromosomes pair up and exchange genetic material through a process called crossing over. Tetrads consist of two homologous chromosomes, each made up of two sister chromatids.
What are two sets of chromosomes that code for the same trait called?
Homologous chromosomes.
When corresponding portions of chromatids on two homologous chromosomes change places what has occured?
This is called genetic recombination or crossing over. It results in the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic diversity in offspring.

This is the process in which two chromosomes exchange DNA during prophase of meiosis?
This process is called crossing over. It involves the exchange of genetic material between homologous chromosomes, leading to genetic diversity in the resulting gametes. Crossing over occurs during prophase I of meiosis.
What is reciprocal mutation?
when there is a two way exchange of genetic portion between two non-homologus chromosomes, its called reciprocal mutation, its a type of translocation mutation

What are two equal parts of a replicated eukaryotic chromosomes?
sister chromatids
In addition to two sex chromosomes human have 44 other chromosomes called?
autosomes

Homologous chromosomes.

Two chromosomes that have the same lenght centromere position and staining pattern are called?
homologous chromosomes
During prophase a homologous pair of chromosomes consists of?
During prophase, a homologous pair of chromosomes consists of two chromosomes, one from each parent, that are similar in genes but may have different alleles. They come together and pair up to form a tetrad, where they can exchange genetic material through a process called crossing over. This exchange of genetic material increases genetic diversity in offspring.
What are the X and Y chromosomes called?
The X and Y chromosomes are called the "Sex Chromosomes". Both the X and Y chromosome are part of the "sex-determining system" that helps determine the sex characteristics in humans. In the system, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY).
