Explanation:
The total number of degree of freedom in a chi-square analysis is given by following equation
[tex]D_f= N-1[/tex]
Where "N" represents the total number of sample or total number of classes of offspring in a cross.
For instance, in a monohybrid cross, the total number of classes of offspring in this cross is two, thus degree of freedom is one. However, in a dihybrid class the total number of classes of offspring in this cross in F1 generation is four, thus degree of freedom is three.
In F2 generation, the total number of class of offspring still remains four in number irrespective of number of individuals in each class. Thus, in F2 generation too the number of degree of freedom in chi square Analysis will remain 3
The maximum quantity of free values that are rational in the set of data is called the degree of freedom.
The number of degrees that should be used for chi-square analysis is three.
This can be explained as:
- The number of degrees of freedom is given as:
[tex]\text{D}_\text{f} =\text{N -1}[/tex]
In the above equation, N represents the total sample or the offspring classes in a cross.
- In the case of a monohybrid cross the total offspring class is two so the degree of freedom will be:
[tex]\text{D}_\text{f} =\text{2 - 1} = 1[/tex]
- In the case of a dihybrid cross, the F1 generation has four numbers, therefore,
[tex]\text{D}_\text{f} =\text{4 - 1} = 3[/tex]
The degree of freedom will be three.
Even in the F2 generation, the quantity of the class remains the same and hence the degree of freedom will be three.
