Mendel crossed pea plants that had yellow-round seeds withplants that had green-wrinkled seeds. The first generation producedplants with all yellow-round seeds. Self crossing of these plantsproduced the following F2 phenotypes:
| Yellow-Round | Yellow-wrinkled | Green-round | Green-wrinkled |
| Count | 315 | 101 | 108 | 32 |
The expected phenotypic ratio is 9:3:3:1
1. What are the null and alternate hypotheses for the chi-squaregoodness of fit test?
2. What are the expected counts under the null hypothesis?
3. Determine a chi-square test statistic and P value
4. Do you accept or reject the null?
