- A Determine the precise nucleotide sequence of a gene
- B Test whether observed phenotype ratios fit expected Mendelian ratios
- C Directly measure the recombination frequency between two loci
- D Determine the nucleotide sequence of an RNA transcript
Correct answer: B. Test whether observed phenotype ratios fit expected Mendelian ratios
Explanation: Chi-square test: statistical test for goodness-of-fit. Compares observed vs. expected offspring ratios to test if deviations are due to chance or real genetic differences.
