Question 1

1. Among the combinations of attributes described below,
   select the one that would not be suitable for a genetic
   system used in parentage testing analysis.
   a. The system has multiple alleles in Hardy-Weinberg
   equilibrium
   b. The system has a high mutation rate
   c. Databases of allele frequencies are available for all
   ethnic groups tested by the laboratory
   d. All systems selected are genetically independent from
   each other

Answer 1

b. The system has a high mutation rate

   frequency distribution continuous (not discrete)?

   c. RBC antigens
   d. RBC enzymes

Answer 2

a. DNA polymorphisms by RFLP
