Humans typically have 46 chromosomes, arranged in 23 pairs. This includes 22 pairs of autosomes and one pair of sex chromosomes (XX for females and XY for males). Variations in chromosome number can lead to genetic disorders, such as Down syndrome, which is caused by an extra copy of chromosome 21.
in meiosis one crossing over occurs and only two daughter cells are created with the normal amount of chromosomes. though in meiosis II those two daughter cells create another two cells and this time they are haploid not diploid with only half of the normal amount of chromosomes. this is because meiosis mainly occurs in sex cells such as sperm and eggs. they are created with only half the normal amount of chromosomes so that when a sperm and egg fuze to form a zygote, they have the normal amoujnt of chromosomes
With twice the amount of chromosomes in the parent cell, each daughter cell can have a normal number of chromosomes after the cell splits in mitosis.
Gametes, or sex cells such as the sperm or ova contains half the number of chromosomes so that when they combine they have a normal and full set of chromosomes.
No, 29 chromosomes is not a normal number for a female. Typically, females have 46 chromosomes, consisting of two copies of 23 chromosomes.
The normal monoploid (n) # of a female sex cell is 23 chromosomes
Normal amount unless the cell has yet to undergo cytokinesis, in which case it will have double the amount of chromosomes.
the same number as the amount of times i did your mother

Each gamete, the sperm or the egg, is haploid and contains half the number of chromosomes of a normal cell. When the sperm and egg combine to form a zygote, the zygote becomes a diploid cell with the normal amount of chromosomes.
With twice the amount of chromosomes in the parent cell, each daughter cell can have a normal number of chromosomes after the cell splits in mitosis.
It must join with the other gamete to form a diploid number of chromosomes. If it had a diploid number to begin with, the result would be twice the normal amount of chromosomes. A normal cell had "2n" number of chromosomes, and each gametes have "n". If they had "2n" to begin with, the resulting zygote would have "4n", which is clearly not normal in human genome.

The answer is 40
The normal monoploid (n) # of a female sex cell is 23 chromosomes
No - haploid cells contain half the normal amount of chromosomes.Polyploid is the term used for a cell/organism with more than 2 sets of chromosomes.
There are 23 haploid chromosomes in a normal human gamete (sex cell).
