Answer:
Anaphase of meiosis II
Explanation:
I think you are asking during which phase of cell division sister chromatids are mostly likely to fail to separate properly, a phenomenon that can lead to genetic disease.
This is sometimes called non-disjunction, and it is most likely to occur in anaphase during meiosis II. During this stage, sister chromatids of the two daughter cells produced by meiosis 1 are separated and brought to opposite parts of the cell. If something goes wrong at this stage, the sister chromatids can fail to separate properly, meaning the daughter cells do not have the correct number of chromosomes (see attachment).
An example of such a genetic disorder is Down syndrome
Answer: stage of fruit ripening, characterised by a surge of respiratory activity and usually coinciding with full ripeness and flavour in the fruit.
Photosynthesis and food transport has to rely on the plant to respond to the direction of the light.
The cell membrane is composed of two layers of lipids and proteins. These two layers are responsible for what is allowed to leave and enter the cellular membrane.
The three adaptive advantages of the mammalian anatomy are
as follows:
No eggs. Mammals have
well developed offspring that they can keep it safe inside their body until the
time it is ready to be in the outside world.
Four legs under the body. It allows mammals to be highly
developed when it comes to speed.
Fur. It protects the mammals’ skin.
