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.
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.
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 ...
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.
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.
Thomas Hunt Morgan's Drosophila melanogaster genetic linkage map. This was the first successful gene mapping work and provides important evidence for the chromosome theory of inheritance. The map shows the relative positions of allelic characteristics on the second Drosophila chromosome.
Drosophila is a genus of flies of the family Drosophilidae. It comprises over 1600 described species, [ 1 ] [ 2 ] but is estimated to have several thousands. [ 3 ] Alfred Sturtevant divided Drosophila into a number of subgenera , including Drosophila , Sophophora , and Dorsilopha .
Drosophila Genetic Reference Panel (DGRP) is a suite of Drosophila melanogaster lines derived from an out-crossed population in Raleigh, North Carolina. The founders of these lineages were collected from the Raleigh State Farmer's Market [ 1 ] 35°45′51″N 78°39′47″W / 35.764254°N 78.662935°W / 35.764254; -78.662935
