Drosophila melanogaster
Within a few years of the rediscovery of Mendel's rules in 1900, Drosophila melanogaster (the so-called fruit fly) became a favorite "model" organism for genetics research.
Some of the reasons for its popularity: ...

 


Drosophila melanogaster (from the Greek for black-bellied dew-lover) is a two-winged insect that belongs to the Diptera, the order of the flies.

Drosophila melanogester: Common fruit fly. It contributed heavily to the study of genetics because of its ease and speed to breed. It contains only four pairs of chromosomes. See Flybase website.

1 Drosophila paulistorum
Dobzhansky and Pavlovsky (1971) reported a speciation event that occurred in a laboratory culture of Drosophila paulistorum sometime between 1958 and 1963.

Drosophila melanogaster is not the only model organism for developmental genetic studies. Starting in the 1960s geneticists interested in developmental questions turned to a free-living soil nematode, Caenorhabditis elegans.

A Drosophila oocyte is a polarized cell. The future anterior-posterior axis of the fly is established by mRNA molecules that are differentially localized within the oocyte.

In Drosophila (fruit flies), the chorion (eggshell) gene is copied many times in certain cells of the oviduct. These cells make large quantities of the protein needed to surround the egg.

The Drosophila Project A report on the fruit fly and it's contribution to the Genome Project. Maps and some illustrations.

A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is recessive, w+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, ...

A gene in Drosophila, located on the X chromosome, that is a sex switch directing development toward femaleness when it is in the on state. It is regulated by numerator and denominator elements that act to influence the genic balance equation (X/A).

It is present in 38 predicted gene products within the human genome, but only in 12-13 in Caenorhabditis elegans and Drosophila melanogaster.

Tracking the genetic effects of global warming: Drosophila and other model systems This online article looks at the spread and microevolution withing the common fruit fly, Drosphilia and possible relationahips of this speciation and global warming.

The term proposed by Koller (1935) to describe the multistranded condition (Gk. polys, many; tania, ribbon) of the chromosomes found in certain specialized tissues such as the salivary glands of Drosophila.

syncitium - multinucleate cell; may arise either from karyokinesis without cytokinesis (e.g., Drosophila syncitial blastoderm) or from fusion of mononucleate cells (e.g. vertebrate skeletal muscles).

Model organisms for developmental biology include the round worm Caenorhabditis elegans,[38] the fruit fly Drosophila melanogaster,[39] the zebrafish Danio rerio[40], the mouse Mus musculus,[41], and the weed Arabidopsis thaliana.

Dosage compensation The imbalance caused by having two copies of the X chromosome in females compared to only one copy in males is countered (in humans) by X inactivation or (in Drosophila) by reducing the relative level of activity of X linked ...

The most common ones are the yeast saccharomycetales (the same one you use in bread), fruit flies (drosophila), nematodes, mice, zebrafish, and there are a few others like rats that are often used as well.
