The frequency of two- and three- to five-cell clones increases after triple heat-shock. The average number of two- and three- to five-cell cell clones per brain for the non-heat-shocked control (blue; n = 33 brains) and triple heat-shocked animals (orange; n = 12 brains). Error bars denote standard error of the mean; the asterisk indicates p < 0.05 (two-tailed) Mann-Whitney U and Student's t-test.
