Gene flow moves alleles between populations; chromosomal aberrations are structural/numerical changes to chromosomes.

Gene flow (or gene migration) occurs when individuals move between populations and interbreed, carrying their alleles into a new gene pool; it tends to reduce genetic differences between populations and is an important source of variation and a factor affecting the Hardy-Weinberg equilibrium. Chromosomal aberrations, on the other hand, are changes in the normal structure or number of chromosomes. Structural aberrations include deletion (loss of a chromosome segment), duplication (repetition of a segment), inversion (a segment reversed in orientation) and translocation (a segment moved to a non-homologous chromosome); numerical aberrations (aneuploidy/polyploidy) involve gain or loss of who …
