CASE STUDY
GIVEN THIS SCENARIO:
Mr. and Mrs. Reyes died in a tragic accident when they went to a private island for a vacation. Authorities found that they have a lot of money in the bank and bought treasury bills in the stock market. The couple is known to have a son, from whom they are estranged. This man is the sole heir to the Reyes’ fortune. Five men showed up, each claiming to be the couple’s long-lost son who ran away after a misunderstanding with his father. You are called in as a genetics expert to decide who the rightful heir is. You will need to develop a Punnett square based on the genotype of the deceased to eliminate the imposters. A successful result will identify the true heir.
