How many cells are in a karotype?
A karyotype is the number and type of chromosomes within the nucleus of a cell of a species. Given that definition, the karyotype is within the cell. There can be no cells within the karyotype.
When does the chromosome duplicate itself in its life cycle?
will replicate itself during the synthesis phase within its life cycle
Where are sex chromosomes found?
The sex chromosomes will usually be in the last place on the karyotype (typically the bottom right corner). If/when the karyotype is numbered, the sex chromosomes should be numbered as the 23rd pair.
Is it true or false The length of DNA ina chromosome may be as much as 10000 times as long as the chromosome itself?
True. The DNA in a chromosome is tightly packaged and condensed, so the actual length of DNA in a chromosome can be much longer than the physical length of the chromosome itself. This is possible due to the coiling and folding of DNA around histone proteins to form chromatin, allowing for a significant amount of genetic material to be compacted within a small space.
Where in a cell are prokaryotic chromosomes found?
The region of the cytoplasm containing the DNA is called the nucleoid. The term "nucleus" is not appropriate, as there is no nuclear membrane.In bacteria there is a single chromosome, except in the interval between DNA replication and cell division. The chromosome is called circular, meaning that there are no free ends; the DNA molecule is in a loop.

What can't a karyotype show?
A karyotype cannot show detailed information about specific gene mutations or variations. It also cannot detect chromosomal rearrangements at a very small scale. Additionally, it does not provide information on gene expression levels or functional characteristics of genes.
Is hemophilia visble in karyotype?
No. The X chromosome with the mutation will look no different than any other X chromosome. In order to see the mutation you would have to actually examine the base pairs and sequences. A single reversal, translation, deletion, or mutation of any kind within the specific segment of code can result in hemophilia. This will not result in an overall change in appearance of the chromosome.

Do sister chromatids have the same alleles within a chromosome?
Yes, sister chromatids have the same alleles within a chromosome.
What is a segment of chromosome called?
It is which 2+2=4 got it this is very wrong!
What is the difference between karyogram and karyotype?
A karyogram is a photograph of an individual's chromosomes arranged in a standard format, while a karyotype is the set of chromosomes found within the nucleus of a eukaryotic cell. In simpler terms, the karyogram is the visual representation of the karyotype.

What is an mutation?
An Inversion mutation is a mutation that causes a reversal in the order of a segment of a chromosome within the chromosome, or a gene.
Wher is DNA found?
Within a cell's chromosome.
