Question

I’m confused how to answer part A, B,C,D after completing the data Phenotype o o-E 43113l A-B- aaB- aabb Totals a5335 8.0 ·047 In interpreting this Xe value, you havedegrees of freedom a. b. In this case, do you accept/reject the hypothesis that these data approximate the dihybrid F2 ratio with independent assortment? accep c. What is the probability that the deviations are due to chance alone? Complete the following table for the data given. Determine whether each gene pair is behaving according to Mendel's first law, giving a 3:1 ratio. Note that because F2 data are being considered in this problem, one might reasonably expect each individual trait to behave according to Mendel's law of segregation, giving a 3:1 ratio. d. Accept or reject hypothesis value P value 2. The following are dihybrid testcross data. Do these data approximate the ratio one would expect for independent assortment? Complete the table, calculate the X', and answer the d to our calculations.

Explanation / Answer

In this above table Degrees of freedom=2

Here first we calculate p-value using excel function =CHIDIST(3.55,2) we will get it 0.1695

so P-value > 0.05 so we reject null hypothesis

chi square value=3.55 and its p-value 0.1695

Hope this will be helpful to you. Thanks and God Bless you :-)
