A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid."

2. A chromatid is basically a chromosome - its just connected to another chromatid via a centromere.
The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.
A chromosome is a long, highly coiled strand of DNA. When the cell is undergoing replication, the DNA strand will replicate to form two identical copies, one copy goes to each daughter cell. However, a human cell consists of 23 paired homologus chromosomes to give 46 chromosomes in total.
Chromatids are duplicated during the S phase of the cell cycle. This is when DNA replication occurs, leading to the formation of identical sister chromatids connected at the centromere.
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.
Somatic cell chromosome is made of two identical chromatids
At the beginning of meiosis, copies of chromosomes linked together at their centromeres are called sister chromatids. These sister chromatids are duplicated copies of a single chromosome and are held together by proteins called cohesins.
A duplicated chromosome, with two identical portions attached by their centromere, is referred to as a sister chromatid. Sister chromatids are produced during DNA replication and are important for ensuring accurate distribution of genetic material during cell division.
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.

Two sister-chromatids.Each chromatid consists of a molecule of DNA together with associated proteins. There are two DNA molecules (sister-chromatids) following the replication of DNA midway through the preceding interphase. The sister-chromatids are therefore genetically identical.chromatidschromatidsThe two identical joined chromosomes before cell division begins is called sister chromatids.
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.

The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
During early mitosis, chromatid pairs are held together by protein complexes called cohesins. Cohesins play a crucial role in chromosome segregation by keeping sister chromatids attached until they are ready to be separated during the later stages of mitosis.
