Chi-square analysis - Goodness of fit
In the laboratory, a genetics student crossed flies with normal long wings to flies
with mutant dumpy wings, which she believed was a recessive trait. In the F₁, all
flies had long wings. In the F₂, the following results were obtained:
792 long-winged flies
- 208 dumpy-winged flies
The student tested the hypothesis that the dumpy wing is inherited as a recessive
trait by performing x2 analysis of the F₂ data.
(a) What ratio did the student hypothesis?
(b) Did the x2 analysis support the hypothesis?
(c) What do the data suggest about the dumpy mutation?
