The bivalents are homologous chromosome containing a total of two chromosomes. On the other hand, tetrad is the homologous pair of chromosomes containing four chromosome.

Tetrad
bivalent is another name for tetrad
Crossing over:is a process of (breakage) and (exchange) of parts between two homologous chromatids .Each bivalent (a pair of same chromosomes ) is called a tetrad . Along the length of each bivalent one or more X shaped connections between (non-sister chromatids ) are found ;these CHIASMATA are places where crossing overs have occurred .I hope that's helped .ZIZO-Saudi Arabia
Tetrad (found answer in my 9th grade Biology textbook)
This group, surprisingly enough for a biological named structure, is called a tetrad.
No a mule is not a tetrad, this is due to the fact that the mule has 63 chromosomes. Mules are a hybrid between the horse and the donkey, and are unable to reproduce due to the uneven number of chromosomes.
it is the part on the homologous chromosome that holds the two together once they have crossed over. the point where two homologous non-sister chromatids exchange genetic material during chromosomal crossover during meiosis
A bivalent chemical element has the valence 2 as calcium for ex.
1. In metaphase 1 spindle formation is completed In metaphase 2 spindle formation take place 2. Bivalent are involved in metaphase 1 Bivalents are not involved in metsphase 2
The term Tetrad means a group of four. It can be used in any context when talking about something that has a collective of four such as a tetrad of cats.

Reshufling takes place in tetrad during prophase I of meiosis .
