Is onion haploid or diploid?
diploid
Since the onion (Allium cepa) is a diploid organism having a haploid genome size of 15.9 Gb, it has 4.9x as much DNA as does a human genome (3.2 Gb). Other species in the genus Allium vary hugely in DNA content without changing their ploidy.

How many chromosomes are in each stage of mitosis in an onion?
It is given that the number of chromosomes present in each onion root tip cell is 16. Hence, the number of chromosomes in the cell will be 16 at G1 phase, after S phase and after M phase. Also, if the DNA content after M phase is 2C. Hence, the DNA content at G1 phase will be 2C.
