Chromosome Question - urgent?

When we say "Chromosome" do we mean the "X" or is it a general term for all??

Also how do we get a double-stranded chromosome (aka. the "X")?

    In my science book it says that chromosomes are just the "X" when the cell is not about to replicate then the genetic material is called chromatin and it is a loose jumble insided the nucleus. when the cell is ready to divide the chromatin coils itself up into strands these strands are called chromatid and a chromatid is basically one half of a chromosome. then the two chromatids also called " sister chromatids" connect by a centromere making the "X"

    Chromosome is a general term-- the X chromosome is a chromosome that determines gender (along with MANY other things).

    The double-stranded chromosome (with the "x"-shape) is two chromatids (DNA that's all coiled up) connected at the centromere. These are formed during meiosis. For more information on meiosis, I suggest checking out the animation at

    Well the chromosomes are #ed 1-23 (pairs) but the last pair the 23rd are sex chromosomes which are called X and Y which tell if we are a male or female to determine this XX is for female and XY for male so the DNA from the parents determines the gender

    chromosome is more general than just "X". Your DNA is made of many chromosomes that carry many genes.
