5.1.3.5. Grouping genes based on the deviations

Table 5.1. Genes grouped according to their deviation.

Number of genes Deviation

21934−13102 = 8832 D ≥ 2

21934−21787 = 147 D ≥ 2.3

21934−21862 = 71 D ≥ 2.35

21934−21897 = 37 D ≥ 2.4

21934−21921 = 13 D ≥ 2.5

5.1.3.6. Analyzing the selected 8832 genes

Figures 5.6 and 5.7 further confirm that the No. 4 chromosome is the most
significant chromosome.
