Why are chromosome called doubled chromosomes just before mitosis begins?
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
What are the two copies of DNA on each chromosome that form just before cell division?
The two copies of DNA on each chromosome that form just before cell division are called sister chromatids. Sister chromatids are identical copies of the original chromosome that are created during DNA replication in the S phase of the cell cycle. They are held together by a structure called the centromere.

In a human nucleus just before cell division how many chromatids are present?
Normally in a cell, there are 92 chromatids, 2 per chromosome. However, when the chromosomes have duplicated before mitosis, there are twice as many, or 184.
Are all sex genes in male and female located on the sex chromosome?
No, the sex chromosome will just activate them, for instance, masculine characteristics may be on chromosome 3, the y chromosome will activate these in a man and a second x chromosome will deactivate these in a woman.
