Heterozygous (AB) for the STR locus = Allele (A) x allele (B) = 0.02 x 0.03 = 0.0006

Explanation:

The probability of the heterozygous genotype AB is equal to the product of the probabilities of these two independent events (i. e., independent events represented by allele segregation) = 0.02 x 0.03 = 0.0006
