The normal colony color of the fungus Snookii jersiae is orange. A colleague gives you astrain harboring two recessive mutations: one causes a white color; the second, in the ura1gene, causes auxotrophy for uracil. Diploids constructed from this strain mated to a wild-typehaploid make orange colonies (that are Ura+). However, when this diploid is grown on rich
(complete) media, you notice occasional small pie-wedge shaped sectors that are white.When the diploid is grown on media missing uracil, the white sectors are no longer visible.Propose an explanation for this finding
