a
The number of larvae in each percentage pigmentation level, with column headings indicating the upper limit of the interval. Sixty cells were scored per individual.
b
The change in the mean percentage of pigmented cells due to mutation of E(var)3-9 was highly significant (P < 0.001 for each allele) as determined by a Mann-Whitney U-test.
