Complementation Tests of Distinct Recessive Mutants, 1 Through 8, Produce

question 9

Multiple Choice

Complementation tests of distinct recessive mutants, 1 through 8, produce the data in the matrix below. A plus (+) indicates complementation, meaning the phenotype of the combined alleles is wild type, and a minus (- ) indicates a failure to complement meaning that a mutant phenotype results. Assume that the missing mutant combinations would yield data consistent with the entries that are shown. How many complementation groups are formed by these eight mutants?

• A) 4
• B) 5
• C) 6
• D) 2
• E) 3
