Since we all come from a single cell that's multiplied billions pf times to make us - each cell is an exact copy of itself - therefore the chromosomes are identical.

The only homologous chromosome pair in humans that is not identical is the sex chromosomes, specifically the X and Y chromosomes.
The y-chromosome is only present in males. Men will a y-chromosome identical to that of their father, and his father, and his father, etc.
chromatid
Chiral chromosomes.
yes because all they are, are one chromosome divided directly in half in to 2 identical chromosomes. :-)
Somatic cell chromosome is made of two identical chromatids
The two chromatid arms on a chromosome are known as sister chromatids, which are genetically identical copies created during DNA replication. Sister chromatids are joined at the centromere and are separated during cell division.
if you are a male you have an x and a y chromosome in your twenty third chromosome, thus making them different
A chromosome consists of two identical sister chromatids during the S phase of the cell cycle when DNA replication occurs. This ensures that each daughter cell receives an identical copy of the genetic material during cell division.
Well in eukaryotic cells each chromosome has a telomere on each end (to prevent it from unraveling), but I'm not 100% certain that these telomeres are identical although they contain very long repetitions of the same nucleotides. But in bacteria the chromosome is ring shaped and is all genes (there are no noncoding sequences, e.g. centromeres, telomeres, introns, pseudogenes, transposons) so there are no identical parts.
The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.
