A It cannot convert sugar to starch.
B It cannot photosynthesize.
C It has no chloroplasts.
D It has no chlorophyll.

Keeping in view that, the sugar in corn is rapidly converted to starch after the corn has been picked. After picking, corn with the Sh2 gene was found to have more sugar and less starch than corn without this gene.
"It cannot convert sugar to starch It cannot photosynthesize It has no chloroplasts It has no chlorophyll" is the statement that is most likely to be true about corn with this gene.
The correct answer is option A, that is, it cannot convert sugar to starch.
The SH2 gene enormously elevates the concentration of sugar in the endosperm, and that is, why the SH2 varieties of corns are also known as supersweets. The seeds of these varieties exhibit very minimal starch in them, so they look shrunken and are less in weight in comparison to the other sweet corn seeds. The SH2 gene slows the transformation of simple sugars to starch.
