If the endosperm has 36 chromosomes, determine the chromosome number of the male and female gametes.

12, 12

The correct answer is option (1) - 12, 12

If the endosperm has 36 chromosomes, it implies that it is triploid (3n) because the normal chromosome number in most cells of the body is diploid (2n). In angiosperms, the endosperm is typically formed by the fusion of one sperm nucleus with the two polar nuclei in the central cell of the embryo sac during double fertilization.

Since the endosperm is triploid, it means that it contains three sets of chromosomes.

If the ploidy of the endosperm is 3n and the chromosome number is 36, we can determine the haploid number by dividing the chromosome number by the ploidy level.

Haploid number = Chromosome number / Ploidy level Haploid number = 36 / 3 Haploid number = 12

Since the male and female gametes are haploid, the chromosome number in both the male and female gametes would be 12.

Therefore, the correct answer is (1) 12, 12.
