You are studying a new species of eukaryotic microorganism, and observe by microscopy that its nucleus contains exactly 2 linear chromosomes. From this basic information, you can conclude:

a) the cell is probably haploidb) the cell is probably diploidc) no conclusion on the ploidy of the cell can be made with this informationd) the species must have small genome, compared to human cells

Option D

Explanation:

The species probably has a small genome that is made up just two linear chromosomes such as that seen in the Jack jumper ant genome. It containing exactly two linear chromosomes could be a single pair of homologous chromosomes thus maybe indicating the cell is probably diploid but this is not enough to conclude on the ploidy.
