What else can I help you with?
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.
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
The two identical portions that are attached by their centromere are known as?
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.
What is a chromosome has been duplicated the two indentical portions that are attached by their centromere?
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.
What do chromosome contain?
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.
During crossing-over what happens to portions of chromatids?
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.
What is a process in which homologous chromosomes exchange portions of their chromatids during meiosis?
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.
What happends when corresponding portions of chromatids on two homologous chromosomes change places?
crossing over.

What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What crosses over during crossing over?
Each chromatid can synapse with any one it want/chooses.
The two identical portions that are attached by their centromere are known as?
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.
What is a chromosome has been duplicated the two indentical portions that are attached by their centromere?
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.
Once a chromosome has been duplicated the two identical portions that are attched by their centromere are know as what?
chromatids.
What happens in the tetrad stage?
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.
What do chromosome contain?
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.
How does the stock exchange work?
When companies need money the stock exchange allows them to sell small portions of their company to interested parties who become stockholders. The value of these stocks fluctuates as the company increases and decreases in value due to earnings reports and other information provided to the public.
