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.

Meiosis is a type of cell division. It is a duplication process that produces two genetically identical daughter cells from a single parent cell. A tetrad is the foursome during miosis made by two homologous chromosomes. During mitosis no tetrads are formed. So, In humans, the number of tetrads formed during mitosis is null.

Recording from single neurons in the brain has shown that neurons responding to specific types of stimuli are often clustered in specific areas. These results support the idea of localization of function.

Localization of function is an idea used in neuroscience. It refers to the idea that functions can be attributed to specific regions of the brain (different brain areas are specialized for different functions).
