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.
The diagram below illustrates which type of chromosomes that may cross over and exchange portions of their chromatids during meiosis?
what type of cell has two sets of chromosomes
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.
What is the definition of recombination of genetic material?
DNA recombination refers to the phenomenon whereby two parental strands of DNA are tied together resulting in an exchange of portions of their respective strands. DNA recombination results in the process leads to new molecules of DNA that contain a mix of genetic information from each parental strand. There are 3 main forms of genetic recombination. i. Homologous recombination ii. Site-specific recombination iii. Transposition www.examville.com
Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
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 crosses over during crossing over?
Each chromatid can synapse with any one it want/chooses.
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 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.

Yes if eaten frequently and/or in large portions. It is very high in sodium and fat.

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.
