Table 3. Combined Chi-Square value statistics across all replicas for mitosisa.

χ2 0.001 [8]  = 24.482 >0.00186, thus highly significant [32]
a

The different fungal isolate serves as a replica of the same statistical test for mitosis.

b

Chi-square value as determined from the original replica isolates as shown in supplementary information (Table S1) for that specific isolate.

c

Lowest possible probability score associated to that chi-square value determined by R programming [32].

d

The logarithmic value of the probabilityc.

*

The formula used to derive the sum of all the separate tests for each replica.

The number of degrees of freedom is established by taking twice the number of separate tests and probabilities carried out initially (thus 2k  = 2(4)  = 8 degrees of freedom). A 99.999% level of confidence was applied.
