The number of man is a number between 1 and 666. This is a total guess but it may be 616
" a fragment of the papyrus 115 gives the number as 616" google this
Genotype Combinations in Family Pedigrees
Genotype Combinations for Unsampled Individuals:
- If some members of the parental generation are not sampled, the number of possible genotype combinations can be much larger.
- This depends on the number of alleles (k) at each locus. For example, if k=5 among the sampled individuals, we need to account for a potential sixth allele present among the unsampled individuals.
- Consider a two-locus haplotype (combination of alleles at two different loci). With 5 alleles at each locus, there are 6×6=36 potential two-locus haplotypes.
- Each unsampled individual can have 36×37/2=666 potential different genotypes.
Total Parental Genotype Combinations:
- In a family where only full siblings are sampled, we consider 666×667/2=222,111 distinct parental genotype combinations.
- Each of these combinations must be tested against the offspring’s genotypes.
Simplifying the Problem:
- To manage complexity, prior examination of single-locus incompatibilities between parental and offspring genotypes can eliminate many parental genotypes.
- Algorithms can help identify compatible parental genotypes based on observed offspring genotypes.
Polymorphism Levels:
- The complexity increases exponentially with the number of alleles (approximately the eighth power of k).
- Researchers often restrict themselves to moderately low levels of polymorphism (k≤5) to handle the computational load.
