In forensics, a DNA sample is analyzed to determine which alleles of 13 SSR loci are present.How is the probability of that specific combination of SSR alleles existing in the population calculated?

A)The frequency of each genotype is known from determining which allele is the rarest for each locus and then determining if the individual sample contains those alleles.
B)The total number of alleles for all loci in the population is calculated.
C)The Hardy-Weinberg Law is used to predict the genotype frequency at each locus.
D)The total number of alleles in the population is multiplied by 2.
