When corresponding portions of chromatids on two homologous chromosomes change places what has occured?
crossing-over
What is a chromosome has been duplicated the two indentical portions that are attached by their centromere?
Sister Chromatids
The two identical portions that are attached by their centromere are known as?
cromatids b for Plato students
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 do chromosome contain?
Chromosomes contain genes, regulatory portions, the centromere, the telomere and "junk DNA".
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"
During crossing-over what happens to portions of chromatids?
breaks off and attach to adjacent chromatids on the homologous chromosome
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.
Once a chromosome has been duplicated the two identical portions that are attched by their centromere are know as what?
chromatids.
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.
