Question

Quizplus · Accepted Answer

The expression for this scenario is known as the paternity index, which is calculated by comparing the probability of the child's genotype given the alleged father is the biological father, to the probability of the child's genotype given a random man from the population is the biological father. This gives an indication of how many times more likely it is that the alleged father is the biological father compared to a random man from the population. The paternity index can be used to support or refute paternity claims.
