Question
Master regulatory genes play critical roles in development. Predict the MOST likely fate of a fly embryo where master regulatory genes were nonfunctional due to mutation
a) Cell division would stop, and the embryo would halt development.
b) The embryo would be a collection of undifferentiated cells because they never get the message that will send them down a determination pathway.
c) The embryo would be a combination of differentiated and undifferentiated cells because, even in the absence of a functional master regulatory gene, some cells will differentiate on their own.
d) The embryo would continue to develop, but there is a high probability that some limbs may end up in the wrong place in the adult.
