- On the deformity of the female sexual organ of the triple-crescented silkworm moth
抄録
Suzuki has got a mutant which is provided with a supernumerary pair of crescent patterns on the first abdominal segment of the silkworm larva in F2 of Chinese No. 4 (p) _??_×Hakuryu (p+)_??_. This mutant is similar to the supernumerary-crescent silkworms found by Tanaka and Kogure, but differs from those in one point that it has no extraordinary legs. Suzuki called it the “Double-crescented” silkworm.<br>“.ouble Crescents” segregate Double crescents and the normal in a ratio of 2:1 in sibmating. This ratio may easily be understood by assuming that “Double Crescents” (ED) is dominant to the normal pattern (p+), but is reccessive as to the lethal function.<br>In crossing of ED and the “Additional Crescent” (ECa) which has one supernumerary pair of Crescent spots on the third abdominal segment, four phenotypes ED, ECa, ED/ECa and p+ segregated in a ratio of 2:2:1:2. This is comprehensible by assuming that of ED, ECa and p+ are in allelic relations.<br>While ED, ECa and p+ are fertile, ED/ECa is absolutely sterile. The cause of the sterility is due to the deformed sexual organ of the female moth, in which the ovaries are developed normaly, but two oviducts are connected in the proximal ends with each other and formed a single tube, without connected to ovipositor, so that no egg is allowed to come out.
