What is the purpose of meisosis?
|
The purpose of meisosis is to reduce the number of chromosome sets from diploid to haploid.
|
|
|
How many cells are produced as a result of meisosis?
|
4 daughter cells
|
|
|
Why is it important in the life cycle of animals that gametes are haploid?
|
Because the gametes(eggs and sperm) will join another gamete and combine to make 23 pairs of chromosomes. If an animal was a diploid it would duplicate each time meaning by the time it was Adam and Eve's children they would have 46 chromosome's in their gamete which meant their children would be at 92 so on and so forth.

|
What happens to the chromosomes in: Interphase
|
The chromosomes aren't visible but they are being duplicated.
|
|
|
What happens to the chromosomes in: Prophase I
|
The chromosomes become visible. The cell contains a homologous pair of chromosomes. Chromosomes begin to move toward the cell equator
|
|
|
What happens to the chromosomes in: Metaphase I
|
One chromosome of the homologous pair is on one side of the cell equator while the other is on the other side of cell equator.
|
|
|
What happens to the chromosomes in: Anaphase I
|
The pair of homologus chromosomes are seperated. One chromosome moves toward each pole, guided by the spindle apparatus.
|
|
|
What happens to the chromosomes in: Telophase I
|
Nothing happens to the chromosome; meaning no replication will happen between the end of meisosis I and meisosis II
|
|
|
What happens to the chromosomes in:Prophase II
|
Chromosomes move toward the metaphase plate
|
|
|
What happens to the chromosomes in: Metaphase II
|
The chromosomes are on the metaphase plate
|
|

|
The chromosomes are on the metaphase plate
|
|
|
What happens to the chromosomes in: Anaphase II
|
Sister chromatids of each chromosomes now move to as two newly individual chromosomes toward opposite poles.
|
|
|
What happens to the chromosomes in: Telophase II
|
Chromosmes arrive at opposite poles. They then begin to decondensing.
