2 a female and male:
fertilization
If gametes were diploid, that would mean the zygote would get 46 chromosomes (in humans that is) from his father and 46 chromosomes from his mother, that would add up to 92.
There are 23 in both a sperm and egg cell. These unite to form a zygote, which has 46 chromosomes.
The possible gametes are ABDEf, aBDEf, ABDef, and aBDef.
4. Two gametes get together to make something new. Just double up!
23 chromosomes
If gametes were diploid, that would mean the zygote would get 46 chromosomes (in humans that is) from his father and 46 chromosomes from his mother, that would add up to 92.
Since the gametes contain one half the number, the zygote will have to have the full number of 40.
The answer is 40

When a zygote is diploid it obtains two sets of chromosomes. Gametes contain one set of chromosomes. Therefore, 6 chromosomes would amount to 3 sets of gametes.
When a zygote is diploid it obtains two sets of chromosomes. Gametes contain one set of chromosomes. Therefore, 6 chromosomes would amount to 3 sets of gametes.
The gametes must have half as many chromosomes as normal body cells because they unite to form a zygote, which is the first body cell of the new organism. For example, human body cells have 46 chromosomes and human gametes (sperm and egg cells) have 23 chromosomes. When the sperm fertilizes the egg, the zygote will have 46 chromosomes, and is the first body cell of the new human.
There are 23 in both a sperm and egg cell. These unite to form a zygote, which has 46 chromosomes.

To prevent the chromosome number from doubling every generation.Sexual reproduction involves two cells (gametes) combining their chromosomes. The process is fertilization, and the product is a zygote.If each gamete has a single set of chromosomes (as happens in humans, most other animals, and many plants) the zygote will have two sets of chromosomes. Whatever the zygote grows into, whether a person, pelican, or pineapple, every cell in the body will have two sets. If the gametes also have two sets each, the next zygote will have four, and so on, until you need a wheelbarrow to carry your chromosomes around!So every life-cycle that includes a doubling of the chromosome number also includes a halving, and that process is called meiosis. Meiosis occurs at different times in different life-cycles. In humans meiosis happens when the gametes are being formed, but in plants it happens when spores are being formed.
Zygote=2 Gamate=1
