Case Study: The Genetics of Resistance to HIV Infection

CCR5 Genotype Test
Here are the results of testing the CCR5 gene in three individuals: an EU man, one of his parents, and a control individual (not necessarily in that order).

Use the results to determine each person’s genotype. Then determine which one is EU.

INSTRUCTIONS:
First, determine the correct genotype for the individuals.

Then select which individual is EU.
