No. The reproductive cells (eggs, sperm, ova and pollen) all contain half the number of chromosomes of an organisms body cell. This means that at fertilization the two reproductive cells (or gametes) combine to form a single cell with the appropriate number of chromosomes.If a gamete had more chromosomes than a normal cell then fertilization would lead to even more chromosomes and an offspring that would be seriously genetically compromised.
The answer is................46.
92. That zygote would never reach maturity. It would be aborted very early if it ever divided at all
The same reason any creature that uses sexual reproduction: a means to give half of their chromosomes to mix with another half in order to create a genetically diverse offspring.

A cell undergoing mitosis has twice the usual number of chromosomes for that species. For example, human body cells have 46 chromosomes, but after DNA replication, which must occur before mitosis, a human body cell will have 92 chromosomes.

If your talking about mitosis than it would still have 32. Chromosomes Copied ( 64) Divided into 2 daughter cell ( each have 32 ) ...................................Hope that helped
The ultimate function is to divide reproductive cells while cutting the number of chromosomes by half. To do this, two divisions occur instead of one. The number of chromosomes must be halved from 46 to 23 because reproductive cells will combine to make a complete set of 46. If meiosis did not halve chromosomes, the amount of chromosomes in every human cells would double each time. This would be very disorganized and eventually make it impossible to reproduce.

The 'body' cells have 42 chromosomes. The sex cells would have 21 chromosomes. 3 X 7
Human kidney cells are body cells, so they would have 46 chromosomes.
A turkey has 80 chromosomes, so its sex cells will have 40 chromosomes.
Body cells, like liver cells, are diploid. This means they have pairs of chromosomes. In this example the diploid number of chromosomes is 24. In sperm cells (or egg cells) the number of chromosomes is halved. This is described as the haploidnumber. In this example the haploid number would be 24/2 = 12. So the number of chromosomes in the sperm cells would be 12.
