A haploid cell is a sex-chromosome without pair. A diploid cell is a sex-chromosome with pairs . People have 22 chromosome pairs and 2 chromosomes they do not have pairs. A man has XY chromosomes and a woman XX chromosomes.
The two chromatid arms on a chromosome are identical copies.
There are 46 chromosomes per cell, with 22 pairs and an XX pair for females or an XY pair for males.
DNA ?
homologous chromosomes are chromosome pairs that code for the same features such as eye color or hair color, one chromosome of the pair comes from your mom and one from your dad so no they are not identical
When chromosomes are visible, they exist as replicated DNA, so each chromosome consists of two identical sister chromatids, which will be separated during mitosis to form two new identical daughter nuclei.
each chromosome consists of two identical "sister" chromatids

Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
