How do the numbers of chromosomes in normal body cells compare with the number of chromosomes in sex cells?

gametes typically have exactly one half the number of chromosomes of body cells.
This makes sense because two gametes are combined through fertilization to make a new cell with a full set of chromosomes.
In some instances, the gamete has an extra chromosome because the chromosomes don't segregate properly during meiosis. This causes a condition called trisomy, and can cause disorders like Down syndrome

∙ 10y agoIn the human body there are 23 pairs of chromosomes (46 in total); in reproductive cells there are only one half of the pair (or 23 in total).
During fertilization the 23 from the male sperm cell fuse with the 23 from the female ovule and recombine as two pairs of 23 chromosomes (46 again in total).
Normal human cells are diploid (2n), while sex cells are haploid (n)

How do the number of protons and electrons compare in a normal atom?
They are equal
How does the number of chromosomes in sex cells compare with the number of chromosomes in the body?
Sex cells have 23 chromosomes compared to the body cells' 46 chromosomes. This is because a child is created from half the genome of its father and half the genome of its mother. In other words, 23 chromosomes in the mother's egg and 23 chromosomes in the father's sperm, when combined generate a child with 46 chromosomes in its body cells. However, sometimes mutations occur where more of fewer chromosomes are passed down, this will either result in no embryotic development or the embryo having some kind of syndrome.
Why is this important each of the haploid sex cells has only half the number of chromosomes as the original diploi d cell?
Gametes (or sex cells) are haploid in nature. This means they have half the number of chromosomes present in a regular body cell (or somatic cell). The male and female gametes unite in a process called fertilization to give rise to the offspring. Since both the male and female gametes have haploid number of chromosomes, the final offspring will end up having the diploid number of chromosomes.
What is atomic numbers?
Atomic numbers are the number of protons and electrons in a atom.
What element has the atomic number for 3.14?
No element has this atomic number. All atomic numbers are whole numbers.
How does the number of chromosome in a persons gametes compare with the numbers of chromosomes in the body cells?
There are half as many chromosomes in gametes than in normal body cells.
How do the numbers of chromosomes in cells compare with the number of chromosomes in sex cells?
The mother gives the egg and the father gives the the sperm and wine they come to get it can make a zygote in other words the baby
Compare the numbers of chromosomes in different species?
The chromosome number is specific for each type of organism. The exact chromosome number must be maintained for the species to continue. This means that as cells reproduce, the new cells must have the same number of chromosomes as did the original cells
How does a number of chromosomes in a person's sex cells compare with the number of chromosomes in the body cells?
In the sex cells you only have half of the number of chromosomes- 23 instead of 46 which is what you have in your other body cells This is because when the sperm fertilizes the egg, the two nuclei fuse together and the chromosomes combine so you then have the right number for normal body cells to develop in the baby.

Compare the number of chromosomes in a human skin cell to the number of chromosomes in a human egg cell?
yes it has 23 cells.
How does the number of chromosomes at the end of meiosis compare to the number at the beginning?
It's homicide.
Why do reproductive cells need to have half the normal number of chromosomes?
Humans and other organisms that reproduce sexually need to have half the normal number of chromosomes to make sure their offspring have the same number of chromosomes as they do - the father and mother each contribute half of their chromosomes (sperm and egg).
How does the number in chromosomes in sex cells compare to the number of chromosomes in cells formed during mitosis?
it compares by 50% or by half of chromosomes because there are 23 sex cells and 46 chromosomes
