WebAlmost all the fish sampled from the Hudson and the nearby Hackensack River carried the six base pair deletion, but the mutation was extremely rare in other populations. This is exactly what we’d expect to observe if selection favoring the mutation were strong in the Hudson and if the mutation were not advantageous in less polluted waters. WebFeb 27, 2010 · Abstract. Fluorescence in situ hybridization (FISH) is a powerful technique used in the detection of chromosomal abnormalities. The high sensitivity and specificity of FISH and the speed with which the assays can be performed have made FISH a pivotal cytogenetic technique that has provided significant advances in both the research and … tsb found card
