Very large chromosomal rearrangements can be seen microscopically as changes in banding patterns.
Many rearrangements are detectable by changes in linkage or effects on meiotic products.
Crossing-over during meiosis within an inverted region in an inversion heterozygote leads to imbalanced gametes, so it appears from resulting viable gametes that recombination is suppressed within that region. Transposable elements are segments of DNA that can move from one position to another in the genome. The McGraw-Hill Companies. Any use is subject to the Terms of Use and Privacy Policy .
