4. You have determined that the gene order for three linked genes being studied is A B C. The number of recombinants resulting from crossover between genes A and BC are 44 and 48, respectively, while the double-crossover progeny total 4 and 6. What is the recombination frequency between genes A and B if the total progeny from the cross is 1000? Show all of your work.

Expert Solution
Step 1

The frequency of recombination is a metric of genetic linkage that is used to create a genetic linkage map. The frequency with which a single chromosomal crossing occurs between two genes during meiosis is called recombination frequency ().
