The results were consistent with the preliminary observations from Figure 5 A: there was a significant correlation between the core genes and rare genes with the λ parameter, with a highly significant strong negative correlation between the core genes and λ ( p -value < 2.44 × 10 −6 and a correlation coefficient of −0.910, and the explanatory power of the linear model R-squared reached 0.829).
