Question

(c) A DNA profile was generated from a crime stain. 4 peaks were observed at one locus. The areas of the allele peaks are given in the table below. Allele designation Peak area 19 1400 20 7086 21 1128 23 7186 Calculate the relative ratios of the mixture and assuming the larger contributor is female and the smaller one is male, estimate the ratio of X to Y [12 marks]

Step 1

Step 1: Calculate the total peak area by adding up all the peak areas: Total peak area = 1400 + 7086 + 1128 + 7186 = 16800 Show more…
