This video explains in detail the advanced population genetics reports of the Extended Edition - including bulk calculation of inbreeding and genome uniqueness, founder analysis including founder equivalents and founder genome equivalents, mean kinship computation and the calculation of the kinship/relationship matrix.
This is a long video - 20+ minutes. If you're interested in all of the advanced population genetics reports then this is the one to watch.
But if you're only interested only some, there are separate smaller videos you might prefer - see: bulk computation of inbreeding, genome uniqueness and pedigree completeness , how to display kinship/relationship matrix , computation of mean kinships for the breeding pool and founder analysis including computation of founder equivalents
There is also a separate video which you are recommended to watch first that explains about the test data and how to set up a breeding pool.

1. The ancestral inbreeding coefficient is computed using the method of Ballou, JD. ("Ancestral Inbreeding Only Minimally Affects Inbreeding Depression in Mammalian Populations", Journal of Heredity 1997, 8:169-178).
2. The pedigree completeness index is computed using the method of MacCluer et al ("Inbreeding and Pedigree Structure in Standardbreed Horses", Journal of Heredity 1983, 74:394-399).
3. Founder equivalents and founder genome equivalents are computed using the method of Lacy, RC. ("Analysis of founder representation in pedigrees: Founder equivalents and founder genome equivalents". Zoo Biology 8:111-124, 1989.)
4. The number of effective ancestors is computed using the method of Boichard, D, Maignel L, and Verrier, E. ("The value of using probabilities of gene origin to measure genetic variability in a population". Genetics Selection Evolution, 1997; 29(1): 5-23.)
5. Fisher's reproductive value 'Vx' ("The Genetical Theory of Natural Selection". Fisher, R., 1930.)
6. Gene drop analysis and genome uniqueness is described in MacCluer et al ("Pedigree analysis by computer simulation", Zoo Biology 5, 147/160, 1986).
