Two STR Loci Were Determined to Have the Following Allele

Essay

Two STR loci were determined to have the following allele frequencies in the general population:
$$\begin{array} { l l l } & \text { STR A } & \text { STR B } \\\text { Alleles: } & \text { 1A: } 0.1 & \text { 1B: } 0.4 \\& 2 \mathrm {~A} : 0.55 & 2 \mathrm {~B} : 0.4 \\& 3 \mathrm {~A} : 0.25 & \text { 3B: } 0.2 \\& 4 \mathrm {~A} : 0.1 &\end{array}$$
A suspect in a criminal trial was genetically tested for these loci and was found to have the genotype (1A,1A)for STR A and (2B,2B)for STR B-homozygous for both loci.What is the probability that a randomly sampled person from this population would also have this genotype?
