Reciprocal Crosses, Chi-squared goodness of fit test

reciprocal cross

A pair of crosses between the male of one strain and the female of another; and vice versa

What are the female F2 phenotypic ratios when setting up a reciprocal cross for an X-linked dominant mutation where the parental mutant is female and homozygous and parental male is wildtype?
A) 100% mutant
B) 75% mutant; 25% WT
C) 50% mutant; 50% WT
D) 25% mutant; 75% WT

C) 50% mutant; 50% WT

A) 100% mutant
B) 75% mutant; 25% WT
C) 50% mutant; 50% WT

C) 50% mutant; 50% WT

True/False: You cannot do a chi-squared test on F1 generation results because
some expected values are 0, which violates the assumptions of the chi-squared test.
A) True
B) False

B) False
