Problem: To determine whether the mutations in the seven strains leading to the wingless phenotype are in the same gene, your lab sets up complementation tests. You obtain the following results ("+" indicates that complementation was observed; "-" indicates that no complementation was observed). mutation 1 2 3 4 5 6 7 1 -2 - -3 + + -4 - - + -5 + + - + -6 + + - + - -7 - - + - + + -How many different genes are contributing to the wingless phenotypes in these mutant fly strains?
FREE Expert Solution
Recall: Mutants in the same complementation group do not complement each other (negative result)
: Mutants in different complementation groups complement each other (positive result)
