What is a duplicated chromosome?
Understand the Problem
The question is asking for the definition and explanation of what a duplicated chromosome is, which involves understanding the concepts of chromosomes and genetic material.
Answer
A duplicated chromosome is a chromosome with one or more duplicate copies, forming sister chromatids.
A duplicated chromosome is a chromosome that has undergone a specific kind of mutation, resulting in the production of one or more copies of any piece of DNA, including genes or entire chromosomes. These copies are called sister chromatids.

A duplicated chromosome is a chromosome that has undergone a specific kind of mutation, resulting in the production of one or more copies of any piece of DNA, including genes or entire chromosomes. These copies are called sister chromatids.
More Information
Duplicated chromosomes are essential during cell division, ensuring that each daughter cell gets an identical set of genes.
Tips
A common mistake is confusing duplicated chromosomes with homologous chromosomes. Duplicated chromosomes (sister chromatids) are identical pairs formed from a single chromosome during DNA replication, while homologous chromosomes are a pair of chromosomes, one from each parent.
