The paired chromosomes are called Bivalent or tetrad chromosome.

- Four: the cardinal number that is the sum of three and one
- A tetrad is an area 2 km x 2 km square. The term has a particular use in connection with the British Ordnance Survey national grid, and then refers to any of the 25 such squares which make up a standard hectad.
- In biology, meiosis (pronounced) is a process of reductional division in which the number of chromosomes per cell is cut in half. In animals, meiosis always results in the formation of gametes, while in other organisms it can give rise to spores. ...
- In general relativity, a frame field (also called a tetrad or vierbein) is an orthonormal set of four vector fields, one timelike and three spacelike, defined on a Lorentzian manifold that is physically interpreted as a model of spacetime. ...
- The tetrad is the four spores of a yeast or Chlamydomonas, that separate after mating. If the two parents have a mutation in two different genes, the tetrad can segregate as the parental ditype (PD), the non-parental ditype (NPD) or as the tetratype (TT).
- The tetrad or number four is the first number formed by the addition and multiplication of equals. To the Pythagoreans, this symbol and number represented justice as it is the first number that is divisible every way into equal parts.
- In Riemannian geometry, we can introduce a coordinate system over the Riemannian manifold (at least, over a chart), giving n coordinates
- In music theory, a tetrad is a set of four notes. When these four notes form a tertian chord they are more specifically called a seventh chord, after the diatonic interval from the root of the chord to its fourth note (in root position close voicing). ...
- (Tetrads) based on a square, this relationship is formed when four colors equally spaced on the color wheel are used (example: green, blue, orange, red). This color relationship is more varied and can easily become un-harmonious without variation in value or saturation.
