How many number of chromosomes are present in rice?

The rice genome (Oryza sativa; AA genome) is composed of 12 chromosomes (2n = 24) and has a total length of 430 Mb (megabase, a nucleotide length of 1000 000 base pairs) corresponding to about 1500 cM (centiMorgan, a genetic unit of length measured by the crossing‐over frequency in genetic recombinations at meiosis) ( …

What is meiocyte rice?

A meiocyte is a “diploid (2n) cell”, which undergoes reductional division (meiosis) to produce “four haploid (n) gametes”. Endosperm of flowering plants (such as the rice plant) is triploid (3n), due to the “fusion of a male gamete” (n) with the secondary nucleus (2n) during double fertilization.

Are Meiocytes haploid or diploid?
