Joey Tribbiani conducts a Chi-square test and obtains a Chi-square value of 4.0. He sets the significance level Alpha at 0.05. When he consults the Chi-square table, he concludes that the null hypothesis cannot be rejected. How many degrees of freedom are there in Joey Tribbiani's test?(a) 1 (b) 2(c) Less than 1Could be both (b) and (c)

Suppose you decide to test the null hypothesis that the phenotypic ratio in the F2 generation of a monohybrid cross is Dominant:Recessive = 3:1. How many degrees of freedom are there in this Chi-square test?12345

Jon Snow conducts a Chi-square test and obtains a Chi-square value of 4.0. He sets the significance level Alpha at 0.05. When he consults the Chi-square table, he concludes that the null hypothesis must be rejected. How many degrees of freedom are there in Jon Snow's test? (a) 1(b) 2(c) Less than 1(d) both (b) and (c)

Suppose the G allele is dominant while the g allele is recessive. An organism with the genotype GG or Gg will display the G+ phenotype, while an organism with the gg genotype will display the G- phenotype. What would be the predicted phenotypic ratio for offspring if you mated Gg x Gg?4G+ : 0G-3G+ : 1G-1G+ : 3G-1G+ : 1G-
