I am reading the book Molecular Genetics of Bacteria 4th ed. and I don't fully understand the concept/visual representation of dimer chromosomes. Consider the following quote (pg 35):
an odd number of crossovers occurring between any 2 sequences on the 2 daughter DNAs in the dimer will resolve the dimer, but an even number of crossovers will recreate a dimer.
In panel 2, did another recombination event occur to yield 2 daughter chromosomes with the same sequences? The colors made me think they each might not have had their original complete sequence.
Thank you for the answer to my crossover occurrence question and their relation to dimer formation and resolution.
