(A) Distribution of chromosome number per cell is not significantly different from a log-normal distribution (n = 681, χ2 goodness of fit test, h = 0, p = 0.2621). Most cells contain 4 chromosomes with values ranging from 1 to 10. (B) Chromosome copy number is correlated to cell length (n = 660, r = 0.7519, p<0.001), suggesting chromosome duplication is coupled to cell growth.
