Number of chromosomes in the meiocyte of onion, potato, housefly, humans and Ophioglossum are respectively

The correct option is A 16, 48, 12, 46, 1260
Introduction to meiocytes
Meiocytes or gametocytes are the gamete mother cells present in diploid organisms that undergo meiotic division to produce haploid gametes.Thus the chromosome number of meiocytes is the same as the chromosome number of the somatic cells of an organism and is double the chromosome number of its gametes.

Onion
The number of chromosomes present in the meiocytes of onion is 16.

Potato
The number of chromosomes present in the meiocytes of potato is 48.

Housefly
The number of chromosomes present in the meiocytes of housefly is 12.

Human
The number of chromosomes present in the meiocytes of humans is 46.

Ophioglossum
The number of chromosomes present in the meiocytes of Ophioglossum is 1260. It is known to have the highest number of chromosomes in the living world.

Final answer
(c) 16, 48, 12, 46, 1260
