They don't gain cells. If you are referring to Down syndrome it is because there is a mutation in the chromosomes of the DNA. Specifically, the chromosome # 21. The DNA is within the cell.

What are the cells that result from cell division?
zygotes
What is a 7 letter word for cell division?
gametes, zygotes
Which cell has tail to help it move?
Sperm cells are zygotes (specialised cells with only 23 chromosomes).
When does the first mitotic division occur in zygotes?
You remain as a single cell for about 1/2 hour
How are identical twins genetically from fraternal twins?
Identical twins are genetically the same, because they come from the same fertilized egg/sperm cell zygote, which happens to split into two viable zygotes. Fraternal twins, however, come from two different egg/sperm cell zygotes, that are concurrently fertilized and remain viable.
What is total number of cell division during formation of 50 zygotes?
Zero. The zygote is the first cell formed by the fertilization of an egg by a sperm cell. It doesn't divide during it's formation, but it does divide afterwards.
How do jellyfish protect zygotes?
A jellyfish protects Zygotes by Stinging anything that will try to harm it
How many cell does each dividing cell form?
Generally, two. However, when forming zygotes, that is, reproductive cells for eggs or sperm, they split in to 4, each containing half of the genome.
Do all zygotes develop?
No.
What do zygotes grow into?
embryo
Are zygotes capable of developing into a multicellular structure without fusion with another cell?
Yes they are, zygotes themselves are the product of fusion between two haploid gametes. These gametes fuse in order to develop into a multicellular structure, which they are unable to do unless they fuse. The product of their fusion is a zygote which is able to develop into a multicellular structure.
What results in fertilization?
zygotes :)
