In humans tetrad forms only in meiosis and there is no tetrad formation during mitosis
Further explanation
What is tetrad
It is formed during the main 1st of meiosis. It is the foursome of chromatids that structures when alignment of replicated chromosome occurs. It must be for crossing over to happen. It separates when the homologous chromosomes move far apart in meiosis.
Tetrads formed during meiosis
It forms during prophase of meiosis which is very first stage. In humans four cells produce in last of meiosis, Every cell with chromatids forms tetrad. And 23 tetrads will be produced during meiosis because each chromosome 1-23 will have a tetrad.
Tetrads formed during mitosis
No tetrad is formed in humans during mitosis it is formed only in meiosis .
Meiosis
It is a kind of cell division that outcomes in four cells each with a large portion of the quantity of chromosomes of the parent cell, as in the creation of gametes and plant spores. In this number of chromosomes reduce to half than parent cells.
