Answer: Option A

The unusual form of cell division leads to the cleavage of the nucleus without change in its component structure which means the formation of chromosomes followed by the division of the cytoplasm can be termed Amitosis.
It is cell proliferation that does not occur by mitosis, the mechanism usually identified as essential for cell division in eukaryotes.
Amitosis results in a random distribution of parental alleles.
Amitosis was first described in 1880 by Walther Flemming.
