Why does crossing-over not occur in mitosis?
well from what i understand mitosis is just the replication of a cell, a cell divides into two cells and it is not being effected by any other cell so crossing over cant occur Crossing over occurs in meiosis to create diversity in the genetic material so the offspring is neither identical to father or mother. in mitosis it does not occur because the parent cell is making an identical copy of itself, so the DNA does not need to vary.
What happens during prophase you that does not happen during mitosis?
Prophase is one of the stages in the process of mitosis, the stages of mistosis are : 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. So metaphase, anaphase, and telophase are what happends in mitosis and does not happen in prophase. And what happens in prophase that does not in mitosis is that the sister chromatids that were formed during interphase have shortened and thickened and are now visible with a light microscope.
A cell splits into two daughter cells during?
mitosis or meiosis
What happens during the process of mitosis?
During the process of mitosis, the nucleus divides!
Which of these terms would NOT be associated with DNA during mitosis?
Replication would not be associated with DNA during mitosis.
How do mutations occur during mitosis?
reasorment of chromosomes can occur during meosis by crossing over

How would the human population be different if the crossing over did during meiosis?
Children would probably look more like their parents.
What is the difference of a cell that is formed from mitosis and a cell that is formed from meiosis?
Cells formed from mitosis are diploid and are identical (if no mutations occurred during DNA replication) to the parent cell. Cells formed during meiosis are haploid and are different than the parent cell (due to the process of crossing over). Note that mitosis produced only 2 daughter cells whereas meiosis produces four.
When somatic cells reproduce by mitosis does crossing over take place?
Yes. However, crossing over occurs much less frequently in somatic cells than in meiotic cells. Evidence of mitotic crossing over is the occurence of twin spots in Drosophila and other organisms.

What are 2 sources of genetic variation in a population?
Any two of: Mutations Non-disjunctions during anaphase of meiosis Polyploidy Sexual reproduction e.g. crossing-over/recombination during meiosis IF YOU ARE LOOKING FOR THE STUDYISLAND ANSWER IT IS a population whose members have many different traits
What guide chromosomes during mitosis?
what guides the chromosomes movement during mitosis
When during mitosis do chromosomes along the equator?
Mitosis
What type of chromosome is produced during mitosis?
All chromosomes are reproduced during mitosis.
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
