Equational Division

Equational Division

 

a method of reproduction in animal and plant cells; a rarely used synonym for mitosis. As a result of equational division the initial number of chromosomes in the cell is preserved. Equational division is contrasted with reduction division, or meiosis, as a result of which the number of chromosomes in the cell is halved.

FDR in pollen mother cells resulted in the inclusion of all 14 univalents (or 28 chromatids) in one nucleus, which on equational division led to the production of unreduced, functional gametes.
When all univalents move to one pole, they, in essence, bypass the reductional division of meiosis and then, on equational division, produce unreduced gametes.
In this case, the equational division of the dyads from both groups would yield 30 chromosomes at the periphery of the egg and 30 in the interior.
