Chromatids
One chromosome consists of two chromatids connected by a centromere.
A centromere and a pair of sister chromatids
During metaphase in mitosis, sister chromatids line up in the midplane of the cell before they are separated and pulled towards opposite poles.
Chromatids are the two identical copies of DNA that make up a replicated chromosome. They are joined at the centromere and separate during cell division, ensuring each daughter cell receives an identical set of genetic information.
Somatic cell chromosome is made of two identical chromatids
Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis. Each homologous pair consists of four chromatids (two from each chromosome), and crossing over occurs between a pair of chromatids from each homologous chromosome. This results in the exchange of genetic material between the chromatids.
Two chromatids connected at the centromere make up one chromosome.

Describe the chromatic that make up a chromosome when a cell is ready to split
Human cells typically have a total of 92 chromatids, with 46 chromatids being in each set of sister chromatids that make up a chromosome pair during mitosis.
The structure at the center of the chromosomes where sister chromatids are attached is called the centromere. It serves as a point of attachment for the spindle fibers during cell division and helps in the proper segregation of genetic material to daughter cells.
The chromatids line up at the equator of the cell during the metaphase of meiosis. After which the chromatids separate to form individual chromosomes.

The triangle and rhombus pattern block shapes can be combined to make up a trapezoid.
When four sister chromatids come together, they form a structure called a tetrad during meiosis. This occurs during prophase I, when homologous chromosomes pair up and exchange genetic material through a process called crossing over. The tetrad allows for genetic recombination between the sister chromatids, increasing genetic diversity.
