Bayesian networks describing the independence assumptions between nucleotides. The nodes represent random variables, while the arrows describe the conditional independencies between the variables. The left figure (A) shows the base in the reference genome g, the base in the sample a, and the observed base x, while the right figure (B) also includes the alternated (biased) base b.
