From this analysis it is apparent that among every 128 individuals 
18 would be barred and 110 white, both the barred and the white 
birds being equally divided between the sexes as follows:

It is thus apparent that, among every 128 individuals, one would 
expect to find 18 barred birds, equally divided between the sexes. 
The actual results of the 1913 matings may now be compared with 
these expectations, derived in accordance with the second hypothesis.
