of these oothecae were reared and brothers and sisters were randomly 
inbred. The results from the females of the four oothecae were as

The 2 left-rotating females have been inbred with their brothers but 
the females have not yet matured, as of this writing. 
The offspring from 
several oothecae 
of the left-rotating female 
shown in Table 1, were inbred and the direction of rotation of the 
resulting females was 
recorded with the following results (these 
females were discarded after the eggs in 
the first ootheca hatched) :

The 13 right-rotating females from ootheca number 1 (above) were 
reared and the F x individuals were randomly mated to their brothers. 
Each female oviposited from 3 to 5 times, producing a total of 57 
oothecae all of which were rotated to the right. The offspring of 12 
of the above F x females were randomly inbred to their brothers and 
all of 202 F 2 females that were reared rotated their oothecae to the 
right. 
The one levorotating female from ootheca number 3 (above) was 
mated to a brother and their offspring were mated to 2 different 
males (A and B) that originated from the same ootheca. Four of 
the five females mated to male A produced 3 to 4 oothecae each 
(total of 13), all of which were rotated to the right. One female 
produced 3 oothecae all rotated to the left. Unfortunately, this 
female did not mate and none of the eggs hatched. The six females 
mated to male B each produced 3 oothecae (total 18) all of which 
were rotated to the right. The one left-rotating female from ootheca 
number 5 (above) has been inbred but the offspring have not yet 
matured. The offspring of the females mated to brothers A and B 
were inbred and the results of these crosses were as follows:
