Spots of pigmentation are a characteristic that varies considerably in different species of Drosophila.  In the Figure provided below there is a phylogenetic tree that includes information on species that have spots (indicated by the black circle) and those that lack the spot (indicated by the open circle).  The percentages at the nodes representing hypothetical common ancestors in these lineages is the probability that the indicated ancestor had wing spots.    From the following species, identify those that are appropriate to study the underlying molecular basis for the gain of the wing spot characteristic.    多项选择题
