James Walker Family Tree - Inbreeding degree

Description

This report displays found ancestors, the coverage rate, the implex factor and the degree of inbreeding.

The coverage rate is the ratio between known ancestors and possible ancestors (column % below).

An implex is a person appearing several times in the ancestors tree. As a result, the implex factor is the ratio between the cumulated number of ancestors and the number of different ancestors.
Example: if an individual has 100 ancestors, but only 80 are different, the implex ratio is 1 - (80 / 100) = 20%.

The degree of inbreeding is the probability that two alleles of this individual are the same. This means that parents are sharing one or more common ancestors.
