Question

What is the chromosome number of the gametophytic phase in angiosperms?

Options

• 3n (triploid)

• 2n (diploid)

• 4n (tetraploid)

• n (haploid)

Answer 1

The gametophytic phase is haploid with a chromosome number of n. This means it contains only one set of chromosomes. The gametophytic phase develops from spores produced by meiosis and is characterized by having half the chromosome number of the sporophyte.
