What will happen to dna sequence variation in the regions of the genome immediately adjacent to an allele undergoing a selective sweep, or strong positive selection? group of answer choices increased variation and the absence of linkage disequilibrium at nearby sites no change in local genetic variation decreased variation and the absence of linkage disequilibrium at nearby sites decreased variation and high levels of linkage disequilibrium at nearby sites increased variation and high levels of linkage disequilibrium at nearby sites
