Answer: In order to increase genetic variance both egg and sperm undergo meiosis, which results in 4 cells. In oogenesis most of the cells cytoplasm is conserved by one cell known as the ovum. This increases the chance of fertilization and survival of the egg. The remaining three cells are the byproducts of meiosis and are known as polar bodies. They are eventually degraded.
Answer: Start day one - 1 cell Start day two - 4 cells Start day three - 16 cells Start day four - 64 cells Start day five - 256 cells Start day six - 1024 cells Start day seven - 4096 End day 7 - 16,384 cells
This answer is so wrong that it is funny....the ignorance of the person who answered it is really in question. BTW, Downs Syndrome is caused by a genetic defect of the subject having one extra chromosome.
The lower sperm counts or lower production of the Ova sometimes will effect the ability to have children
I believe that this is a repeat of a question,,,,it has been posted several times with nearly identical wording.
Answer: There are more than two if you were to disect the testes. Two than come to mind are sperm cells and blood cells but there are also other tissue cells such as skin cells. Perhaps you need to rephrase the question.
