Task: Answer Verification
Input (English): Question: Is release of developmental constraints on tetrad shape confirmed in inaperturate pollen of Potamogeton?
Answer: The data support the view that there is a correlation between the inaperturate pollen production and the release of constraint on tetrad shape. However, in P. pusillus the tetrad shape may be constrained by a callose ring. It is also suggested that the lack of apertures in the pollen of Potamogeton may be due to the lack of specific sites on which callose deposition is completed. Moreover, inaperturate pollen of Potamogeton would be better classified as omniaperturate.
Output (English): yes
