The recessive autosomal gene ivory (i) causes white eyes in the flesh fly Sarcophaga barbata. The mutation completely blocks the synthesis of formylkynurenine. Ivory larvae and ivory imagoes are able to synthesize xanthommatin if formylkynurenine and kynurenine respectively are provided with the food. The eye colour of the F2- and the R1-mutants… CONTINUE READING
