How many chromosomes are there when a human egg and sperm fuse?

That depends on the species.
In the case of humans, egg and sperm cells have half of the chromosomes of a regular cell - 23 chromosomes each.
When they join, the resulting cell will have the complete 46 chromosomes.

∙ 14y agoThere are 46 chromosomes, in 23 matching pairs.
Egg and sperm cells are haploid, meaning they only have one copy of each chromosome, rather than the two copies that the somatic (non-reproductive) cells of the body have. The egg contains one copy of each of the 22 autosomal chromosomes and one X chromosome. The sperm contains one copy of each of the 22 autosomal chromosomes and either one X or one Y chromosome. After fusion, these pair up to form a diploid cell, so that there are 46 chromosomes - two of each of the 22 autosomal chromosomes, and either two X chromosomes, or one X and one Y chromosome.

How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
How many chromosomes do each human egg cell have?
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.
How many chomosomes in your body?
In a normal Human body cell (not a gamete) there are 46 chromosomes. This is not the same number of chromosomes in our bodies, only in one cell, and there are trillions of cells in the human body. In a gamete (a sperm cell or egg cell) there are 23 chromosomes. When the sperm and egg cell nuclei fuse in fertilisation, a diploid cell of 46 chromosomes is produced.
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.
If each human cell consists of 46 chromosomes how many chromosomes are in each egg or sperm cell?
23
When a human egg and sperm fuse how many sets of chromosomes are there?
46
How many chromosomes are found in human egg and sperm cell?
There are 23 chromosomes in each the sperm and the egg. When they fuse, the resulting embryo will have 46 chromosomes.
How many chromosomes does the human sperm cell have?
It has 23 chromosomes.
How many chromosomes in normal human eggs and sperm is the same as in the body cells?
There are 23 chromosomes in human egg/sperm. In other human body cells there are 46 chromosomes.
How many chromosomes from each egg and sperm?
There are 23 chromosomes from the egg and 23 chromosomes from the sperm making it 46 in total when they both fuse together.
How many chromosomes in human sperm cell?
too many.
How many chromosomes are in each sperm cell?
23. There are 46 chromosomes in a human, half from the egg and half from the sperm.
How many chromosomes are in each sperm produced by a male?
There are 23 chromosomes in each sperm produced by a human male.
How many chromosomes does a human sperm or egg cell contain?
The human egg or sperm cell is haploid and contains 23 chromosomes. After fertilization (egg and sperm fusion), the zygote will have 46 chromosomes (23 pairs).
How many sex chromosomes does a sperm carry?
Each parent donates 23 chromosomes to fertilization process however only the male can determin the sex.
How many chromosomes are in 50 sperm cells?
I assume you mean human sperm cells.Haploid and n = 23 chromosomes, so......23 * 50= 1150 chromosomes===============
How many chromosomes do each human egg cell have?
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.
