NEET Biology question
The triploid number of chromosomes of the first taxon is 10 times more than the haploid number of chromosomes of the second taxon, while the diploid number of the third taxon is six times more than the haploid number of the fourth taxon. Which one of the following shows the ascending order of the number of chromosomes in their respective endosperm?
Answer: (B)
Solution
Using the known haploid chromosome numbers Oryza (n=12), Allium (n=8), Saccharum (n=40) and Nicotiana (n=24): if the first taxon is Saccharum (3n = 120) and the second is Oryza (10 × 12 = 120), the first relationship is satisfied. If the third taxon is Nicotiana (2n = 48) and the fourth is
