Certain cell types normally have several nuclei per cell. How could such multinucleated cells be explained?

The cell underwent repeated mitosis, but cytokinesis did not occur.

Explanation:

A cell that has more than one nucleus inside it is known as a multinucleated cell. These multinucleated cells exit two types according to their formation process.

The porocyte process is the most common and proven and is generated by cell mitosis without cytokinesis. That is to say that the duplication of all the genetic information of the cell is generated but the cell division does not occur and therefore all the articles and genetic information remain within the same cell.
