Question
Which of the following is true regarding the number of degrees of freedom in the Mendel's and De Vries' dihybrid cross experiments1. In both experiments the number of degrees of freedom was 4 - 1 =1 because in both experiments they had 4 different phenotypic classes. The 5% critical value for such a number of degrees of freedom is 11.070
2. In both experiments the number of degrees of freedom was 5 because in both experiments they had 3 different phenotypes. The 5% critical value for such a number of degrees of freedom is 3.841
3. In both experiments the number of degrees of freedom was 4 - 3 =1 because in both experiments they had 3 different phenotypes. The 5% critical value for such a number of degrees of freedom is 3.841
4. In both experiments the number of degrees of freedom was 3 because in both experiments they had 4 different phenotypic classes. The 5% critical value for such a number of degrees of freedom is 7.815
5. None of these
I know that the formula is n-1....thats all i know so far.
