There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
FlyBase is an online bioinformatics database and the primary repository of genetic and molecular data for the insect family Drosophilidae. [1] For the most extensively studied species and model organism, Drosophila melanogaster, a wide range of data are presented in different formats.
The Drosophila Interactions Database (DroID) is an online database of Drosophila gene and protein interactions. [1] It was developed by Russell L. Finley's laboratory at Wayne State University School of Medicine in 2008 and has been funded by the National Human Genome Research Institute, National Institutes of Health's National Center for Research Resources, Michigan Proteome Consortium, and ...
The alleles on the chromosome form a linkage group due to their tendency to form together into gametes. The distance between the genes (map units) are equal to the percentage of crossing-over events that occurs between different alleles. This diagram is also based on the findings of Thomas Hunt Morgan in his Drosophila cross.
Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/ [1] [2]) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.
The map shows shows the relative positions of allelic characteristics on the second Drosophila chromosome. The distance between the genes (map units) are equal to the percentage of crossing-over events that occurs between different alleles. Reason High quality, scalable vector diagram of a classic and important scientific result
The homeotic selector genes were discovered through the genetic analysis of Drosophila over 80 years ago [citation needed].Unusual disturbances were found in the organization of the adult fly, resulting in misplaced limbs, such as legs developing where antennae usually develop or an extra pair of wings developing where halteres should be.
