- A Determine the total chromosome number of an organism
- B Estimate relative distances between genes on a chromosome
- C Locate point mutations directly within a gene
- D Determine the nucleotide sequence of a DNA strand
Correct answer: B. Estimate relative distances between genes on a chromosome
Explanation: Genetic (linkage) maps plot relative positions of genes based on recombination frequency. 1 map unit (cM) = 1% recombination frequency.
