← Life Sciences & MedicineIf two genes, A and B, are located on the same chromosome but are far apart, what explains the observed recombination frequency during meiosis?
A)Independent assortment without physical linkage
B)Reduced DNA repair during crossing over
C)Increased gene mutation rates near each other
D)High probability of crossing-over between them✓
💡 Explanation
High recombination frequency occurs when genes are far apart on the same chromosome because there is a greater chance of crossing-over between them during meiosis; therefore, the genes appear to assort independently rather than remaining linked, which would be expected for closely linked genes.
