A zygote, regarded as the first cell of the offspring, is diploid and contains 2n number of chromosomes (the simple algebraic sum of the number of chromosomes in gamete from each parent, represented by "n"). Thus, it contains the same number of chromosomes as either of the parents (2n).
For instance, a human zygote contains 46 chromosomes.

∙ 12y agoHumans have 23 chromosomes, so possible combinations of chromosomes in haploid gamete = 223. Now, 1 gamete from mother and one from father contribute in formation of zygote and thence an offspring. So assuming no recombination occur possible combinations of chromosomes that can be produced is
223x223 = (223)2 = 246. This is of order of 10 trillions (7.03687442 × 1013).
PS:
That is probably greater than the number of humans ever born on face of earth. So probability of 2 siblings who are not identical twins to be almost genetically identical is one in 10 trillions (1.42108547 × 10-14).
If you even consider recombination the number comes out to be somewhere around 252 = 4.50359963 × 1015.
a huge number :D

∙ 13y agoZygotes are produced from the combination of two haploid cells (sperm and egg), so the resulting cell is diploid. In humans, this means that there are 23 pairs of chromosomes (46 total chromosomes).

What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes contain 12 chromosomes each?
It will be 24 in the zygote since zygote is diploid cell and gametes are haploid.
A zygote is from a parent's 23 chromones each when reproducing?
A zygote is a cell that results from the union of two gametes, typically from different individuals. The zygote contains all of the genetic information necessary to form a new individual. This information is contained in the zygote's 23 chromosomes, which are a combination of the 23 chromosomes from each parent.
How does the number of chromosomes in a zygote compare with the number of chromosomes in a body cell?
Double.Each gamete (sex cell) has one copy of each chromosome. Somatic (body) cells have 2 copies.
When gametes combine to form a zygote the chromosomes number of the zygote is now referred to as?
diploid is what the total number of chromosomes in an organism is
What is gamete fusion?
It is the process during the formation of a zygote when two gametes, each carrying a different set of chromosomes, fuse together. This ensures that the developing zygote has a set of chromosomes from each parent and the cells can divide properly.The fusion of gametes is called sexual reproduction. There must be two gametes present for sexual reproduction to occur and they must have to correct number of chromosomes.
If there is 10 chromosomes how many zygote?
A zygote is the combination of the half DNA data from both "parents" and if each have a total of 10 then the Zygote receives 5 from each parent and ends up with the same as its parents' number of chromosomes.
How many chromosomes should a zygote have so the baby's body cell will each have a normal set of chromosomes?
46
How many chromosomes human zygote possess?
46 23 from each parent...unless there is a mutation. Hi sorry to but in, but i was just wondering. If a human zygote contains 46 chromosomes and then total chromosomes they have is 46. Then if a mouse has 40 chromosomes would it's zygote be 40 as well? I have Biology homework and i was just wondering. Thanks!
How many chromosomes does a zygote have and a gamate have?
Zygote=2 Gamate=1
Where are the chromosomes in the zygote?
chromosomes are present in the nucleus of zygote.
How many chromosomes in human diploid zygote?
A normal human diploid zygote contains a full set of 46 chromosomes. A zygote refers to the initial cell that is formed when two gamete cells join together through sexual reproduction.
What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes contain 12 chromosomes each?
It will be 24 in the zygote since zygote is diploid cell and gametes are haploid.
How many chromosomes does s fruit flies zygote have?
8 chromosomes
How many chromosomes would be in a zygote if the bird has 30 chromosomes?
A zygote is a fertilized egg cell, so it is diploid and thus has a full set of DNA. If the adult has 30 pairs of chromosomes, the zygote would have 30 pairs. If there are 30 chromosomes, then the zygote will have 60 (30 from the mother and 30 from the father). It comes down to whether you meant individual chromosomes or pairs of chromosomes.
A zygote is from a parent's 23 chromones each when reproducing?
A zygote is a cell that results from the union of two gametes, typically from different individuals. The zygote contains all of the genetic information necessary to form a new individual. This information is contained in the zygote's 23 chromosomes, which are a combination of the 23 chromosomes from each parent.
How many Chromosomes does the zygote contain?
46 I think
How many sets of chromosomes does a zygote have?
there are 23 sets
