The chromosome number only doubles when two haploid gametes form to produce a diploid zygote. Example: In humans, sperm cells and eggs have 23 chromosomes, the haploid number. Once they fuse, the number doubles to 46 chromosomes. You may be confusing this with chromosome replication. In chromosome replication, the number of chromosomes does not double, but the number of strands double. (A single stranded chromosome turns into a double stranded chromosome.) However, it is still considered a single chromosome, but with identical sister chromatids. This replication occurs during the S-phase of the cell cycle, before mitosis or meiosis.

What is the diploid chromosome number in humans?
The diploid chromosome number in humans is 46.
What is the modal chromosome number?
The modal chromosome number refers to the most common number of chromosomes found within a particular species. It is essentially the number that occurs most frequently among individuals of that species.
What would happen if the chromosome number were not reduced during meiosis?
If the chromosome number were not reduced during meiosis, the resulting gametes would have double the normal number of chromosomes. This would lead to an imbalance in the genetic material when the gametes combine during fertilization, resulting in genetic abnormalities and potentially nonviable offspring.
What is the region of a chromosome holding the two double strands of replicated DNA together called?
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
In which stage of meiosis is the chromosome number halved?
The chromosome number is halved during the first stage of meiosis, known as meiosis I.
What would happen if sex cells were not haploids?
The chromosome number would double throughout each generation.
What happen if meiosis did not occur to produce sex cells?
the chromosome number would double in every generation
What chromosome number is diabetes type 2?
Chromosome number 20.
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
What is the diploid chromosome number in humans?
The diploid chromosome number in humans is 46.
In albinism what chromosome number is affected?
Chromosome 9.
Why is each chromosome a double?
There are 2 of each chromosome because you get 1 set from each parent.
What is the modal chromosome number?
The modal chromosome number refers to the most common number of chromosomes found within a particular species. It is essentially the number that occurs most frequently among individuals of that species.
Does a zygote ha ve a diploid chromosome number?
yes zygote do have diploid chromosome number
What is the chromosome number of an crocodile?
Crocodiles have a chromosome number of 32 pairs, totaling 64 chromosomes.
What would happen if the chromosome number were not reduced during meiosis?
If the chromosome number were not reduced during meiosis, the resulting gametes would have double the normal number of chromosomes. This would lead to an imbalance in the genetic material when the gametes combine during fertilization, resulting in genetic abnormalities and potentially nonviable offspring.
What is the chromosome number in the daughter cell?
The chromosome number for daughter cells resulting from mitosis is the same as the parent cell.
