Subunit of a chromosome after replication and prior to anaphase of meiosis II or mitosis. At anaphase of meiosis II or mitosis when the centromeres divide and the sister chromatids separate each chromatid becomes a chromosome.
Chromatid
A chromatid is one of two identical halves of a replicated chromosome. During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes.

Chromatid: One of two copies of a replicated chromosome during mitosis. Together they are called sister chromatids. Each one becomes a daughter chromosome at anaphase of mitosis and at the second meiotic division.

chromatid A replicated chromosome joined to its sister chromatid by the centromere; separates and becomes daughter chromosome at anaphase of mitosis or anaphase of the second meiotic division.
A chromatid is a single DNA molecule.
Double-stranded chromosomes have two chromatids; normally, each one is identical to the other. The point where the two chromatids are attached is called the centromere.
Condensed chromatid pairs are held together at the metaphase plate by balanced bipolar forces exerted on the chromosomes by kinetochore microtubules in the mitotic spindle.
Label two chromatids with each letter. This way they can line up the pairs of homologous chromosomes during metaphase I and demonstrate all of the phases of meiosis. This leads right into a lesson on dihybrid crosses and probability.

Chromosome Structures found in the nucleus of cells composed of DNA and proteins.
After the DNA is replicated in the S phase preceding meiosis, the homologous chromosomes (each composed of two chromatids) pair up in Prophase I and then crossing over, ...
It is customary in genetics to use strand for chromatid. It has therefore been used in that sense in some books, where it has also been used for one double-chain (that is, duplex) DNA molecule.
During metaphase, cohesion between sister chromatids is maintained by a chromosomal protein complex, cohesin. Anaphase is triggered when separase cleaves the Scc1 subunit of cohesin at two specific recognition sequences.
Anaphase is preceded by metaphase, by the end of which fully condensed sister chromatids are arranged in pairs, their centromeres lying along a surface known as the metaphase plate.
