Hypothetical products generated by recombination mediated by R7, R8, and R10. The black arrows indicate the repetitive sequences R7, R8, and R10 (simply written as 7, 8, and 10) involved in recombination, with the arrow direction showing their orientation. The colored segments represent the DNA fragments C1, C3, C4, C5, C6, C9, and C10 (simply written as 1, 3, 4, 5, 6, 9, and 10) located between these repetitive sequences
