The correct statement is: (2) Sister chromatids are genetically identical.

Sister chromatids are the copies of a single chromosome. These are therefore genetically identical. The sister chromatids are joined together at the region called centromere with the help of certain proteins. The chromatids are formed during the S phase of the interphase due to a process called duplication.

Chromosome is the compact form of DNA. It consists of the genetic material and certain proteins called histone proteins. The main role of chromosome can be seen during cell division. This is because the division of genetic material takes place in the chromosomal form.
