Which of the given statement is incorrect about the Chromosomal Rearrangements? |
| A. | Comparison of the number of rearrangements in a given period of evolutionary history may vary significantly from one organism to the next |
| B. | If gene A has a neighboring gene B, then if an ortholog of A occurs in another genome, there is an increased probability of an ortholog of B also occurring in the other organism |
| C. | If gene A has a neighboring gene B, then if an ortholog of A occurs in another genome, the B ortholog is more likely to be a neighbor of the A ortholog of the genome of the second species if the two species are more divergent |
| D. | In general, the order of orthologs is not well conserved in prokaryotes when the genomes have diverged sufficiently that the orthologs have < 50% identity |
| Answer» D. In general, the order of orthologs is not well conserved in prokaryotes when the genomes have diverged sufficiently that the orthologs have < 50% identity | |
