Only in that way do you get a human zygote - each chromosome MUST be paired
and there must be 46 total to get a true human.
(Note that in reality there are occasional mismatches - either too many or too few - and the result is always a defective child.)

How do the number of chromosomes in a female scorpion's egg cells compare with the number in her body (somatic) cells?
There are 46 chromosomes in your body cells. The egg cells have half the amount of chromosomes as the body cells, so there are 23 chromosomes in the egg cells.
After completeing meiosis 2human sex cells have a total of chromosomes?
No. A sperm cell and an egg cell released from an ovary contain half the chromosomes as other cells until the sperm enters the egg cell and its chromosomes join that of the egg. At that point the egg cell becomes a new individual with a full complement of chromosomes. In humans a person gets 23 chromosomes from the mother and 23 from the father for a total of 46.
What type of cells contain only one set of chromosomes instead of two?
Gametes, also called sex cells, or sperm and egg cells, contain only one set of chromosomes.
What is the importance of producing haploid egg and sperm cells at the end of meiosis?
It is important because the gamete needs to have 46 chromosomes or 23 pairs. If the sperm and egg both contributed 46 chromosomes, then the cell would have 92 chromosomes.
What does it mean when you say 'The sperm and egg are Hapliod cells'?
haploid means only one set of chromosomes that is one chromosomes is present only one time sperm and egg are haploid means that their nucleus have only one set of chromosomes remember that gametes are always HAPLOID therefore egg and sperm are haploid
Do chromosomes only occur in egg and sperm cells?
No, sex cells just have 1/2 the chromosomes of the rest of cells.

Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
Does each egg and sperm cell contain a full set of 46 chromosomes?
No. These cells contain only half the number of chromosomes as the other cells of the body. Each egg and sperm cell contain only 23 chromosomes.
Which cells have only 23 unpaired chromosomes?
The only place you would be able to find a cell with 23 chromosomes would be in the sex cells (sperm cells of egg cells). There are 46 chromosomes in the human body. This is because when a sperm cell fertilises the egg cell, both with 23 single chromosomes, they join to make 46.
Why is it important that the sperm and the egg each have half the normal number of chromosomes?
If the fertilized egg does not have a normal number of chromosomes, this can leads to problems with the child later on. An example is Down syndrome, which is caused when chromosome 21 does not split properly.

Walter suttons important observation was that chromosomes of the egg and sperm cells are located inside the?
nucleus
What type of cells contain only one set of chromosomes instead of two?
Gametes, also called sex cells, or sperm and egg cells, contain only one set of chromosomes.
At the end of meiosis II each of the haploid sex cells has only half the number of chromosomes as the original diploid cell why is this important?
Because then, when the sex cells combine in reproduction, the egg's chromosomes and the sperm's chromosomes will combine to form the original amount of chromosomes in a diploid cell, so it can replicate with a new set of DNA.
How many total chromosomes are typically found in a human cell?
In a somatic cell: 46 chromosomes.In a sex cell: 23 chromosomes.
A pig has 38 chromosomes in each of its body cells how many chromosomes will be in each of the egg cells released by a female pig?
Sex cells are haploid cells, meaning that they have half the cells of body cells. If a pig has 38 chromosomes, then in its egg cells there will be 19 chromosomes. Also in a male pig there will be 19 in its sperm cells.
