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.
It is important to have half the amount of chromosomes in your sex cells than in your somatic cells because your sex cells combine with another sex cell after conception. For example, if you are a woman, your egg has 23 chromosomes because a sperm will come and fertilize it with and have its own 23 chromosomes. Therfore, when the two cells combine, there will be a total of 24 chromosomes. If our sex cells had the normal amount of chromosomes, then when two sex cells combined, there would be 48 chromosomes and that would be too much.
The reason that is, is because sperm and egg cells are haploid(having 23 chromosomes) cellls and in order to reproduce a full working cell it has to be a diploid (having 46 chromosomes) cell. If sperm and egg cells were to have anymore chromosomes then there supposed to then the new cell would have to many chromosomes to even function. Overall its important because that's the only way fertilizatoin can occur is if they have half the chromosomes of a normal cell...

Except in the egg and sperm, all cells are somatic cells and have the normal number of chromosomes.
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
A human egg/sperm cell has 23 chromosomes. When the sperm and egg fuse together,, the zygote (fertilised egg) contains 46 chromosomes. Scientists call this the diploid number, with the sperm/egg having a haploid number of chromosomes. This number varies between species.
gametes are haploid (half the normal number of chromosomes)
Triploidy refers to a condition where an individual has 1.5 times the normal number of chromosomes. Egg and sperm cells are haploid (have n number of chromosomes). Normal cells are diploid (have 2n number of chromosomes). The exact cause of triploidy in humans is not known. It may be caused when more than one sperm fertilize a single egg. Triploidy may be preferred and cultivated in plants in order to increase productivity.
The number of chromosomes found in either and egg of sperm is half the number of chromosomes found in a normal cell of the organism. For example, if you are thinking of a human sperm or egg cell is would be 23 chromosomes, since the normal human cell has 46.
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.
in humans the sperm and egg cells (gametes) have 23, half the number of chromosomes as in normal cells
Except in the egg and sperm, all cells are somatic cells and have the normal number of chromosomes.
Half the number that are in the adults normal body cells
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).
Human gametes are haploid, meaning they have half the normal number of chromosomes. Since our full number is 46, sperm and eggs have 23.
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
I assume you mean human egg and sperm cells. There is a haploid number of chromosomes in these cells. 23 chromosomes. n.
