Answer:
Total 40 sister chromatids
Explanation:
A cell cycle comprises of various phases that includes G1 phase, S phase, G2 phase, Mitosis and cytokinesis.
- During G1 phase the cell grow in size and almost all of the content of cell is duplicated except the DNA. The cell contains chromosome with a single copy of DNA.
- During S phase the the the DNA is duplicated and each cell have chromosome with two sister chromatids.
- G2 phase came after the DNA duplication and recheck the DNA duplication for errors.
As G2 phase occur after DNA duplication so each chromosome in this phase contains two sister chromatids that's why the corn plant with 20 chromosomes would contain 40 sister chromatids in G2 phase.
