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.

Selected Answer: Individual 2

Correct.
Individual 2 has only a Δ32 CCR5 allele so the individual is EU.

Now that you have completed tests on a small number of individuals, click Next to see what this test revealed about the frequency of the allele in the general population.
