Answer to Problem 11E
Explanation of Solution
Given:
Phenotype | Red eyes and straight wings | Red eyes and curly wings | White eyes and straight wings | White eyes and curly wings |
Frequency |
Significance level:
Ratio:
Concept Used:
Null hypothesis:
The null hypothesis is rejected when the value of
Calculation:
The null hypothesis:
The phenotype occur in a ratio of
Alternative hypothesis:
The phenotype does not occur in a ratio of
Now,
Take the sum:
Draw a table consisting of observed value and expected value:
The expected value is calculated as:
Phenotype | Red eyes and straight wings | Red eyes and curly wings | White eyes and straight wings | White eyes and curly wings | Total |
Observed value | |||||
Expected value |
Now, use the test −statistics:
Degree of freedom:
For
So, the null hypothesis is not rejected when the value of
Hence,
The phenotypes occurs in the given ratio
Conclusion:
Therefore,
