When the mother is unavailable for parentage testing, a calculation must usually be based on types determined for the child and the alleged father. Particularly in the case of DNA typing, the formula is easy to derive. The correct formula is apparently not widely known, however, and in fact, a formula that is obviously incorrect seems often to be used and quoted. The correct method of derivation is indicated, and formulae are given for the various possibilities for patterns of gene-sharing between child and alleged father. In most cases paternity = 1/4Pr(shared allele) is an adequate formula.
当无法对母亲进行亲子鉴定时，通常必须根据孩子和被指控父亲的检测类型进行计算。特别是在DNA分型的情况下，公式很容易推导出来。然而，正确的公式显然并未广为人知，事实上，一个明显错误的公式似乎经常被使用和引用。文中指出了正确的推导方法，并给出了孩子与被指控父亲之间基因共享模式的各种可能性的公式。在大多数情况下，亲子关系概率=1/4×（共享等位基因的概率）是一个足够的公式。
