When corresponding portions of chromatids on two homologous chromosomes change places what has occured?
crossing-over
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 genes, regulatory portions, the centromere, the telomere and "junk DNA".
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 in which homologous chromosomes exchange portions of their chromatids during meiosis is the definition of the term "Crossing Over"
What crosses over during crossing over?
Each chromatid can synapse with any one it want/chooses.
What happends when corresponding portions of chromatids on two homologous chromosomes change places?
crossing over.
When corresponding portions of chromatids on two homologous chromosomes change places what has occured?
crossing-over
During crossing-over what happens to portions of chromatids?
breaks off and attach to adjacent chromatids on the homologous chromosome
The diagram below illustrates which type of chromosomes that may cross over and exchange portions of their chromatids during meiosis?

What do chromosome contain?
Chromosomes contain genes, regulatory portions, the centromere, the telomere and "junk DNA".
Some portions of chromosomes are condensed and DNA is not expressed these dark-stained areas are called?
Heterochromatin is dark stained area caused by condensed chromosomes or DNA. Heterochromatin is located near between the inner membrane and the nucleoplasm.
What happens in the tetrad stage?
During the tetrad stage, the metaphase I of meiosis starts to happen. When this occurs, the diploid meiocyte divides twice.

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.
