Select one:
No 
Yes
Cannot be determined
Your answer is correct.
The correct answer is: No
The curly wing mutation is dominant  to the wildtype allele for wing shape.
(a) What is the PREDICTED phenotypic ratio of the F1 progeny from Cross A?
1 straight-winged flies : 1  curly-winged flies
(b) What is the PREDICTED phenotypic ratio of the F1 progeny from Cross B?
1 straight-winged flies : 2  curly-winged flies
(c) Test the fit of your cross B observed class data with that expected based on your hypothesis (b)
using a χ2 test in one of the tables below, for the table you are not completing, enter a '1' into each box.
Give your answers to two decimal places (except for p values - please provide the complete value).
If you predicted a 1 straight wing: 2 curly wing ratio in (b), use this table -
