In the ventral nerve cord of the Drosophila larva, each neuroblast (neural stem cell) divides repeatedly, regenerating itself and generating a transient ganglion mother cell with each division (Figure Q7-4). Each ganglion mother cell then divides to produce two daughter cells. At the end of this process, a full neuroblast lineage is composed of two different types of neurons, A and B, in approximately equal numbers. Figure Q7-4
A. How might these two distinct types of neurons be generated?
B. What are some experiments that could be performed to test this hypothesis?
