tetrads
Sets of four
Tetrads are groups of four.
In biology, a tetrad is the cluster of four chromatids formed when chromosomes pair during cell division, or a group of four spores produced together.
In chemistry, tetrad can describe an element with valence four.
The term appears wherever fourfold groupings matter: The genetic tetrad separated during meiosis.
