WebTo detect the possible presence of a chromosomal imbalance explaining these clustered Mendelian errors the log R ratio (LRR) was subsequently analyzed. All affected piglets showed a drop of LRR in the proximal region (0–25 Mb) of chromosome 8 and, surprisingly, also an increase in the distal region (109–142 Mb) of chromosome 14 (Additional ... WebEach of our chromosomes has a characteristic structure. Historically, scientists have used a staining technique that colours the chromosomes into a banding pattern. These banding patterns make each of our individual chromosomes easier to identify, like a map. A set of chromosomes, as seen under a microscope, is known as a karyotype.
