DNA ?
An original chromosome is called a homologous chromosome, and its copy is called a sister chromatid. Homologous chromosomes have the same genes in the same order but may have different alleles, while sister chromatids are identical copies produced during DNA replication.
During cell division, each chromosome makes a copy of itself through a process called DNA replication. This creates two identical copies of the chromosome, which are then separated into two new cells during mitosis.
A duplicated chromosome consists of two identical sister chromatids joined at the centromere. Therefore, one half of a duplicated chromosome refers to one of these sister chromatids, which contains a copy of the genetic material from the original chromosome.
The structure that holds each chromosome to its exact copy is called a centromere. The centromere is a region of the chromosome that serves as the attachment point for the two sister chromatids, which are the identical copies of the chromosome formed during DNA replication. The centromere plays a crucial role in ensuring the accurate segregation of chromosomes during cell division.
When a chromosome has made a copy of itself, each of the two strands is called a sister chromatid. Sister chromatids are identical copies formed during DNA replication and are joined at the centromere.

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.
A duplicated chromosome consists of two identical sister chromatids joined at the centromere. Therefore, one half of a duplicated chromosome refers to one of these sister chromatids, which contains a copy of the genetic material from the original chromosome.
Before cell division begins, each chromosome consists of two identical joined chromatids called sister chromatids. Each sister chromatid contains an identical copy of the chromosome's DNA molecule.
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.
The structure that holds each chromosome to its exact copy is called a centromere. The centromere is a region of the chromosome that serves as the attachment point for the two sister chromatids, which are the identical copies of the chromosome formed during DNA replication.

Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
When a chromosome has made a copy of itself, each of the two strands is called a sister chromatid. Sister chromatids are identical copies formed during DNA replication and are joined at the centromere.

In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
The only homologous chromosome pair in humans that is not identical is the sex chromosomes, specifically the X and Y chromosomes.
