it is called replication
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
TRUE
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.
A homologous strand of a chromosome is a duplicated copy of the original chromosome, formed during DNA replication. It contains the same genetic information as the original chromosome and is held together by a centromere. Homologous chromosomes play a key role in meiosis, where they pair up and exchange genetic material during crossing over.
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.

TRUE
A chromatid means one copy, or a daughter cell, of a duplicated chromosome, which is joined to another copy by a single centromere. Each contain the same DNA and chromosome protein as the original cell.
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
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.

A cell with two copies of each chromosome is called a diploid cell. A cell with one copy is called a haploid cell.
The condition in which an individual has three copies of a chromosome is called trisomy. It can result in genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21.
Humans who have lost one copy of an autosome are called heterozygous for that specific chromosome. This condition is known as monosomy for that particular autosome.
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.
An identical copy of part of a chromosome is called a sister chromatid. Sister chromatids are produced during DNA replication and are held together by a structure called the centromere. They are important for ensuring accurate distribution of genetic material during cell division.
