Therefore, the number of chromosomes in the endosperm is 72.
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?
Meiocyte is a type of cell that differentiates into a gamete by the process of meiosis. It is a diploid cell. After meiosis, it divides into four genetically different haploid spores (meiospores).
What is the origin of pea?
Peas (Pisum sativum) are original from the Old Continent, although there are many doubts about their true origin. Their use is relatively common in Europe, and they were probably introduced from Palestine or Egypt into European Eastern areas of the Mediterranean sea, considered as the main centre of diversification.
How many chromosomes do daughter cells have?
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.
