Question

You are looking at the phenotypes of offspring resulting from a dihybrid cross for dominant/recessive genes. You expect a ratio of 9:3:3:1 and believe the offspring fall in the range of this ratio but want to check your hypothesis using the Chi-Square test. Your null hypothesis is that the offspring______are or are not__ significantly different from the expected 9:3:3:1 ratio. You calculate a Chi-Square value of 4.056. The degrees of freedom are (2,3,4) and the p-value is(.05,.10,.20,.50). Based on this information, you (acceppt, reject) your null hypothesis.

Explanation / Answer

Your null hypothesis is that the offspring are not significant different from expected ratio

We accept the null hypothesis

Note - the p value is more than 0.05 we fail to reject the null hypothesis . As there is difference between and conclude no significant difference exist.
