Step 4: Select which gene is located in two specific positions on the chromosome. There is a chromosome with seven positions on it called first, second, third, fourth, fifth, sixth, and seventh. Deletion 1 covers positions fourth, fifth, and sixth. Deletion 2 covers positions second, third, fourth, and fifth. Deletion 3 covers positions fifth, sixth, and seventh. Deletion 4 covers third, fourth, and fifth. Deletion 5 covers positions first and second. Deletion 6 covers positions fourth, fifth, sixth, and seventh. Determine which mutation is located at the first position on the chromosome.
