In C. elegans, P granules act as cytoplasmic determinants to assist with the development of the posterior end of the organism. Suppose that P granules were abnormally found in both the anterior and posterior ends of a developing C. elegans organism. What would you expect to observe?
A) The embryo would develop with a normal anterior end and anterior structures on the posterior end.
B) The embryo would develop with a normal posterior end and posterior structures on the anterior end.
C) The embryo would develop with anterior structures on the posterior end and posterior structures on the anterior end.
D) The embryo would develop with a normal anterior end and a normal posterior end.

P granules are responsible for specifying the posterior end of C. elegans. If they are present at both ends, the organism would develop posterior structures at both ends, leading to a normal posterior end and posterior structures on the anterior end.

In C Elegans, P Granules Act as Cytoplasmic Determinants to Assist
