If a chromosome replicates but remains attached does it count as one or two chromosomes?
I don't know weather you mean attached to the chromosome "bundle" (made of chromosomes wrapped in a tight ball) or attached to the cell (as in remaining within the cell membrain).
But chromosomes come in pairs of 23. Every cell (excluding gametes) come with 46 chromosomes which come in 2 sets of 23. this cell would have not 46 but 92 if the chromosomes had replicated but not broken off into a new cell - and so would have 4 pairs of chromosomes, or 2 sets.
This division happens at the start of meiosis and mitosis, however usually they then go on to divide into 2 new cells (and eventually 4 in meiosis)

What happens to the chromosome number during mitosis?
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
Meiossis is cell division in which the number of chromosomes?
Before mitosis begins, the cell replicates its chromosomes (so the chromosome number doubles). Then during/after mitosis the cell splits in half - so each daughter cell produced by mitosis has the same chromosome number as the original cell.
When a cell divides by mitosis how is the chromosome number affected?
In the beginning of mitosis the number of chromosomes double. But since during mitosis the chromosomes are divided between the two daughter cells the number of chromosomes at the end is the same number as the beginning before doubling.
What happens to the chromosomes number when a cell divides?
The chromosome number remains the same during cell division. In mitosis, the cell produces two daughter cells that are genetically identical to the parent cell, each containing the same number of chromosomes. In meiosis, which produces gametes, the chromosome number is halved to ensure the correct number of chromosomes in the resulting offspring.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
How is the chromosome number affected by cell division?
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.
What happens to the chromosome number during mitosis?
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
After replication how many chromosomes exist?
46 duplicated chromosomes. humans have 23 types of chromosomes (n), each with a homologous pair (1 from mom, 1 from dad) giving us 46 total (2n). When cells undergo replication they duplicate all their chromosomes. The duplicate remains attached to the original chromosome by a centromere. The two attached duplicates are called sister chromatids (this is what you see as an x shaped chromosome- 1 chromosome, 2 sisters) which will be pulled apart during anaphase, giving each cell, once they divide, a full set of 46 chromosomes.
Meiossis is cell division in which the number of chromosomes?
Before mitosis begins, the cell replicates its chromosomes (so the chromosome number doubles). Then during/after mitosis the cell splits in half - so each daughter cell produced by mitosis has the same chromosome number as the original cell.
Change in chromosome number in mitosis and meiosis?
In mitosis, the chromosome number remains constant - each daughter cell receives the same number of chromosomes as the parent cell. However, in meiosis, the chromosome number is halved - the resulting gametes have half the number of chromosomes compared to the original parent cell.
What happens to the number of chromosomes in mitosis?
There is no change in chromosome number. Just in the amount of chromatids. Because during synthesis each chromosome doubles and becomes sister chromatids.
When a cell divides by mitosis how is the chromosome number affected?
In the beginning of mitosis the number of chromosomes double. But since during mitosis the chromosomes are divided between the two daughter cells the number of chromosomes at the end is the same number as the beginning before doubling.
Does the chromosome number changes throughout the human life cycle?
No, the number of chromosomes remains constant throughout the human life cycle. Human cells have 46 chromosomes, with 23 inherited from each parent. This number is maintained through cell division and reproduction.
What happens to the chromosomes number when a cell divides?
The chromosome number remains the same during cell division. In mitosis, the cell produces two daughter cells that are genetically identical to the parent cell, each containing the same number of chromosomes. In meiosis, which produces gametes, the chromosome number is halved to ensure the correct number of chromosomes in the resulting offspring.
What is chromosome comparison?
Chromosome comparison is where the DNA of one species is compared to another. For instance, Scientists compare the remains of prehistoric animals to current organisms roaming the Earth in our modern day world.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
In Mitosis how many chromosomes does the parent cell have How many chromosome does the daughter cell have Is this number different or same for parent and daughter cell?
Mitosis, of course.
