AP Bio Chi-Square Problem Quiz

What is the expected phenotypic ratio in a monohybrid cross of Big P Little P crossed with Big P Little P?

• 4:1

• 1:1

• 3:1

• 2:1

When setting up a Chi-Square table, what is the first step?

• Calculate the Chi-Square value

• Subtract observed from expected

• Set up a table with columns for each phenotype

• Square the differences

How do you calculate the Chi-Square value for each phenotype?

• Add observed and expected values

• Divide the squared difference by expected

• Multiply observed by expected

• Subtract expected from observed

What is the significance level commonly used in AP Biology for Chi-Square tests?

• 0.10

• 0.01

• 0.001

• 0.05

What does it mean if the Chi-Square value is greater than the critical value?

• The test is invalid

• The result is insignificant

• Reject the null hypothesis

• Accept the null hypothesis
