4,8
4,7
8,7
4,12
8,12
What term describes when a child inherits the same allele from both parents (5,5)
homozygous

homogeneous
heterogeneous
What is the name of the graphic display that results from STR analysis?
karyotype
PCR
electrophoresis
electropherogram
On an electropherogram, alleles are represented by...
peaks on a graph
letters like AA or Aa
blue dots on a test strip
band on an autorad
If there is only one allele (one peak) on the electropherogram for a particular locus, what does that tell you about the genotype?
the genotype is heterozygous
the genotype is codominant
the genotype is homozygous
the person did not inherit any allesl for that STR loci

D3S1358
vWA
D16S539
CSF-1PO
