A liquid that has a pH of 7 is considered to be neutral (pure water is generally considered to have a neutral pH). Fluids that have a pH below 7 - like lemon juice and coffee-are considered to be acidic. And fluids that have a pH above 7 - like human blood and milk of magnesia-are considered to be alkaline.
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.he result is an egg or sperm with only 23 chromosomes.
