Question: How many chromosomes are found in onion?

Common onion (Allium cepa L.) has eight pairs of relatively large chromosomes (2n = 16) that allows for the easy detection of CAs.

Can onion have 32 chromosomes?

Explanation: Meiocytes are the diploid cells that experience meiosis to deliver gametes (sperm or egg), their chromosome number is the same as that of the organisms. On the off chance that the quantity of chromosomes in meiocytes of onion is 32, at that point, the number of chromosomes in gamete cells will be 16.

How many chromosomes are found in onion and pine cell?

Onion root tip cells have 16 chromosomes in each cell.

How many chromosomes are found in the pollen of an onion?

NEET Question. Meiocyte is a diploid cell i.e. 2n=32, so endosperm of it would have 3n=48 chromosomes.

How many chromosomes are present in endosperm of rice?

Haploid number n = 12. Therefore the number of chromosomes will be n x 3 = 36 because the endosperm in angiosperms is triploid 3n as it is formed by the fusion of 2 polar nuclei n and one gamete. The meiocyte of rice has 24 chromosomes.
