Population genetic indicators

With the power search, select any group of animals. For example, those from 2012.

Mark the entire search result and store it as a group of animals."

This group is available as the top most entry of the ‘Groups of animals’ page.

You can now carry out the calculation for the group, and then look at the population genetic indicators for this group of animals.

The four indicators (inbreeding coefficient, ancestor loss coefficient, integrity index and original part) are determined for each animal.

In addition, the effective population size is calculated using three variants:

"1. the real increase in inbreeding, taking into account the actual increase in inbreeding from the parents to the offspring

2. the estimated increase in inbreeding, taking into account the parents which are effectively used

3. The increase in inbreeding in random pairing (i.e. the parents which are effectively used at the time of the calculation, i.e. still capable of pairing or alive, etc.)"

 

This includes the generation interval, i.e. the age of the parents when they are replaced by their offspring in breeding.
