Allele numbers are listed for each gene according to isolation origins. λ, mean allele number; P(0), probability of unidentified genes; N(0), number of unidentified genes.

^aAssume that the allele frequency observes Poisson distribution. The probability of unidentified genes, i.e., the category with 0 allele, follows P(κ) = λ^κ·e^-λ/κ!. When κ = 0, P(0) = e^-λ.

^bN(0) = N·e^-λ/(1-e^-λ). N, number of identified genes.
