Alright so i can explain this but hold up, i will be back

Answer 9

OK

Answer 10

since i don't have a lot of time right now this might help

also meiosis and mitosis go through PMAT and cytokineses

ooooo this website is very good too

Answer 11

Meiosis

Chromosome abnormalities usually happen as a result of an error in cell division. Meiosis is the name used to describe the cell division that the egg and sperm undergo when they are developing. Normally, meiosis causes a halving of chromosome material, so that each parent gives 23 chromosomes to a pregnancy.

The result is an egg or sperm with only 23 chromosomes. When fertilization occurs, the normal 46 total number of chromosomes results in the fetus. If meiosis does not occur properly, an egg or sperm could end up with too many chromosomes, or not enough chromosomes. Upon fertilization, the baby could then receive an extra chromosome (called a trisomy), or have a missing chromosome (called a monosomy).

While pregnancies with a trisomy or a monosomy may go to full-term and result in the birth of a child with health problems, it is also possible that the pregnancy may miscarry, or that the baby is stillborn (not born alive), because of the chromosome abnormality. In studies of first trimester miscarriages, about 60 percent (or more) are chromosomally abnormal. In studies of babies who are stillborn, 5 to 10 percent have a chromosome abnormality.

Mitosis

Mitosis is the name used to describe the cell division that all other cells, besides the egg and sperm, undergo when they are developing. Normally, mitosis causes a duplication, followed by a halving of chromosome material, so that each cell doubles the number of chromosomes to 92, and then splits in half, so that the normal total of 46 is resumed. Mitosis begins in the fetus after fertilization.

This process repeats itself, until the entire baby is formed. Mitosis continues throughout our lifetime, to regenerate new skin cells, new blood cells, and other types of cells that are damaged or that simply die off.

During pregnancy, an error in mitosis can occur, just like the error previously described in meiosis. If the chromosomes do not split into equal halves, the new cells can have an extra chromosome (47 total) or have a missing chromosome (45 total). This is another way a baby can be born with a chromosome abnormality. Errors in mitosis are responsible for some cases of mosaicism.
