28 Σεπ 2010 · A clear sign that inversions are involved in adaptation comes from geographical variation in their frequency. A dramatic example is the inversion 3RP in Drosophila melanogaster, which has established parallel latitudinal clines on three continents .
A particularly clear example is the European corn borer, Ostrinia nubilalis, where an inversion spanning about 40% of the Z chromosome (~10 Mb) contains both a pheromone receptor locus and a locus contributing to seasonal adaptation of different ecotypes (Kozak et al., 2017; Kunerth et al., 2022).
Origin of Inversions: Inversion was first discovered by Sturtevant in 1921 in Drosophila. Later it was detected in a wide variety of plant and animal species. Inversions occur spontaneously, and can be induced artificially. In many organisms, inversions are found in the natural populations.
20 Μαΐ 2022 · Inversions are a type of variant that can occur in our genomes. They are part of a group of changes known as ‘structural rearrangements’ that include deletions (where large sections of DNA are missing), repeats (or copy number variants) and translocations within the genome.
25 Ιαν 2019 · Early studies of inversions were restricted to species with easily visualised chromosomes (e.g., flies). Today, inferring the presence of inversions is technically possible in many species as reference genomes, genetic maps, and extensive sequencing data become available.
Inversion is a chromosomal rearrangement in which a segment of a chromosome is reversed end to end. This structural change can disrupt gene function and impact genetic expression, leading to various phenotypic consequences.
