By calculating the coefficients of Kinship, Relationship and Inbreeding for any combination of father and mother in the database a lot of statistical information can be shown about the potential children.
This so called "Virtual Mating" can help you make a correct combination by calculating the inbred percentage (coi% or ci%) of potential children. You will be able to see how the (potential) parents relate to each other and which ancestors have the greatist influence on the chosen combination.
To start off with you need to select the parents of the virtual litter. To complete these complex calculations at least the four grandparents need to have been entered into the database. If one of the parents is not shown in the list below it is possible that the pedigree is not "complete" enough to do a proper inbreeding calculation. The more ancestors in the pedigree the better these calculations become. The calculations go back 8 generations so it is important to make the pedigree as complete as possible.
