crossing-over
It's called crossing over, and it generally only happens between homologous chromosomes.
what type of cell has two sets of chromosomes
The two identical portions that are attached by their centromere are known as sister chromatids. They are produced during DNA replication and are separated during cell division.
A duplicated chromosome, with two identical portions attached by their centromere, is referred to as a sister chromatid. Sister chromatids are produced during DNA replication and are important for ensuring accurate distribution of genetic material during cell division.
Chromosomes contain DNA, which carries the genetic information that determines an organism's traits and characteristics. They also contain proteins that help in regulating gene expression and packaging the DNA into a compact structure.
crossing over.
During crossing-over, portions of chromatids exchange genetic material with their homologous chromatids. This results in genetic recombination, where genes are shuffled and new combinations of alleles are created, increasing genetic diversity.
The process is called crossing over or genetic recombination. It results in genetic diversity by shuffling genetic information between homologous chromosomes, leading to unique combinations of genes in the offspring.
Each chromatid can synapse with any one it want/chooses.

During the tetrad stage of meiosis, homologous chromosomes line up in pairs and exchange genetic material through a process called crossing over. This increases genetic variation in the daughter cells. Subsequently, the pairs of homologous chromosomes separate and move to opposite poles of the cell during meiosis I.
Chromosomes contain DNA, which carries the genetic information that determines an organism's traits and characteristics. They also contain proteins that help in regulating gene expression and packaging the DNA into a compact structure.
One of the twelve portions into which the year is divided; the twelfth part of a year, corresponding nearly to the length of a synodic revolution of the moon, -- whence the name. In popular use, a period of four weeks is often called a month.
