Statistics for developing testis analyses. Description of data analysis used in . (A) Box plot of correlations within 10 replicates of each testis development stage. X-axis in (A and B) correspond to microarray experiments performed with testes isolated from either feeding (f) or wandering (w) larva (L) grown for 4, 5, 6, 7, or 10 days at 18°C. Adult flies correspond to 12-15 days of growth . Dashed lines correspond to correlations equal to 0.5 and 1.0; the blue line is the overall average of all correlations (0.72); and the red line shows the minimal correlation found in . (B) Box plot representing the distributions of the standard deviations of 10 replicates for approximately n = 14,000 Drosophila genes (transcripts) in each development stage. Note that the ratio between the standard deviation among genes (orange and blue circles in (B)) and the mean of the standard deviations within replicates of the same gene can be as low as 1.1. X-linked and autosomal statistics are shown in orange and blue, respectively.
