, 1. dCE: ry
2. DCE: RZ
3. Hardy Weinberg equation: Used to calculate allele and genotype frequencies ina population when the frequency of
one genetic trait is known
4. HLA antigens: Certain characteristics of blood group and anti-
gens make them useful tools for parentage analysis
5. Direct exclusion, indirect excursion: Assuming maternity is correct, paternitycan be excluded in one of two ways
6. Genetic markers present in the child
but is absent from the mother and alleged father: Direct exclusion
7. Child lacks a genetic marker that alleged father (given his observed pheno-type) must transmit to his offspring:
Indirect exclusion
8. Example of direct exclusion: If the child is blood group Bmother is blood group O
Alleged father is group O
what kind of exclusion is this, direct or indirect
9. HLA antigens are inherited as haplotypes: HLA antigens are inherited as
10. This is an example of indirect exclusion
It's indirect because we presume the father is JK (b+b+): If the child is Jk(a+b-)Mother Jk(a+b+)
alleged father is Jk(a-b+)
Is this an example of direct or indirect exclusion?
11. Silent gene: Do not overlook the possibility of a when solv-ing
genetic problems
12. Paternity index (PI): Chance that the AF is the biologic father compared to thechance that a random man is the
father
13. Biologic father =genetically proven fatherAF = alleged father
