Imagine that there is a loss-of-function mutation in the gene for the Notch receptor in the progenitor cell of C. elegans. How does that mutation affect vulva development

Hello your question is incomplete attached below is the complete question

answer :  

None of the progenator cells differentiate into type 2 cells. ( A )

Explanation:

Due to the loss-of- function mutation in the gene for the Notch receptor in the progenitor cell of C elegans , This causes The progenator cells for type 1 to be  differentiated to type 1 cells but the cells for type 2 will not be differentiated.

hence the answer is  : None of the progenator cells differentiate into type 2 cells.
