If the diploid number of a gymnosperm is 36, then the number of chromosome in its endosperm is
View answer and explanation
Correct option: B
54
Option B (54) is correct because the endosperm of gymnosperms is formed before fertilization and is therefore haploid (n). Since the diploid number (2n) is 36, the haploid number (n) is 18. The endosperm is the result of the fusion of the egg (n) and the two polar nuclei (n+n), so it is triploid (3n). Therefore, the number of chromosomes in the endosperm is 3 * 18 = 54.
