Question

A geneticist is performing a chi-square test for goodness of fit on data from a genetic cross where 6 genotypes are expected in a 1:1:1:1:1:1 ratio. How many degrees of freedom does this test have?

Answer 1

Hey! So for degrees of freedom you would be required to take however many genotypes there are being tested and subtract that number by 1.

Since there are 6 genotypes, you would do 6-1 and get 5 degrees of freedom :)

Hope this helps!
