Analyze the given data using chi-square test and see if it fits the expected 9:3:3:1 F_{2 }phenotypic ratio.
Ho: Null hypothesis: The F_{2} phenotypic ratio follows the 9:3:3:1.
Ha: Alternative hypothesis: The F_{2} phenotypic ratio does not follow the 9:3:3:1.
Decision criterion:
Accept Ho if chi-square computed is less than chi-square tabular.
Reject Ho if chi-square computed is greater than chi-square tabular.
