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?
Changes 1,2,4, and 7 didn't supplement one another, and thus are on a similar quality.
Changes 3, 5 and 6 didn't supplement one another, however supplemented with transformations 1, 2, 4, and 7. Thus, these three transformations are available together on an alternate quality.
The answer would be A because if they are raised where every th ing is given to them they don't know how to do the normal functions they do naturally by themselves like hunt or maybe migrate.
