This insect is super popular among genetic researchers. Tell us why and also identify the insect.

There are many reasons why this is popular, pls to put the most important one. Not so important ones will also get points.

Drosophila Melanogaster or the common fruit fly – Very easy to breed and has a life cycle of 10 days, which means multiple generations can be observed in a short time.

Points assigned by AutoRaja. Review by lazy humans pending.

    Fruit fly or Drosophilidae

    Important because its genes are modified with relative ease and lend well to experimentation.

  2. jowens

    Drosophila melanogaster (fruit fly). There’s a bunch of reasons it’s popular: it’s cheap, it breeds quickly and lays lots of eggs, it has a simple genome, its genome has been completely sequenced, it has readily identifiable genetic markers, you can put flies to sleep easily (“FlyNap”). (That’s some of why we bred them in high school biology!)

  3. badideabear

    Scientists like these insects because “it is a species that is easy to care for, breeds quickly, and lays many eggs.” The insect is Drosophila melanogaster aka the common fruit fly.

  4. Manish Achuth

    Fruit Fly. Most of the human disease genes have a recognisable genome match in the fruit fly. Hence, used for research etc.

  5. Vishwas B Sharma

    Two of my friends at SDSU are researching on this :)

    This is Drosophila Melanogaster or Common Fruit Fly or Vinegar Fly. It is typically used in genetic research because it is a species that is easy to care for, breeds quickly, and lays many eggs.

  6. Sumanth Patlolla

    Drosophila melanogaster(common fruit fly)- widely used for biological research in studies of genetics, physiology, etc.

  7. Drosophila melanogaster, common fruit fly or vinegar fly.
    used for genetic analysis/ gene mapping etc etc etc.

  8. anurag

    Fruit Fly.

  9. Drosophilia melanogaster – easy to breed

  10. Drosophilia melanogaster is a model organism and is widely used in biological and genetic research, about 75% of known human disease genes have a recognizable match in the genome of fruit flies.

  11. rickde

    fruit fly model organism for bio studies
    first organism used for genetic analysis an best-known of all eukaryotic organisms
    easy to care for, breeds quickly, and lays many eggs
    75% of known human disease genes have a recognizable match in the genome of fruit flies

    Also, like humans, male fruit flies rejected by females drink more alcohol

  12. finkle

    Drosophila is heavily used as a model organism in genetics and the genes of some of its species are quite well sequenced, especialy those who show different (skin?)colors.

  13. Bharath

    Drosophila melanogaster (fruit fly) -They are used as model organisms in genetics because of the similarity of their genome to that of humans and other mammals.

    Drosophila melanogaster
    Its care and culture requires little equipment and uses little space even when using large cultures, and the overall cost is low.
    It is small and easy to grow in the laboratory and their morphology is easy to identify once they are anesthetized (usually with ether, carbon dioxide gas, by cooling them, or with products like FlyNap)
    It has a short generation time (about 10 days at room temperature) so several generations can be studied within a few weeks.
    It has a high fecundity (females lay up to 100 eggs per day, and perhaps 2000 in a lifetime)
    Males and females are readily distinguished and virgin females are easily isolated, facilitating genetic crossing.
    The mature larvae show giant chromosomes in the salivary glands called polytene chromosomes—”puffs” indicate regions of transcription and hence gene activity.
    It has only four pairs of chromosomes: three autosomes, and one sex chromosome.
    Males do not show meiotic recombination, facilitating genetic studies.
    Recessive lethal “balancer chromosomes” carrying visible genetic markers can be used to keep stocks of lethal alleles in a heterozygous state without recombination due to multiple inversions in the balancer.

  15. Ananth

    Drosophila Melanogaster. The ‘superstar’ of genetics research. Easy to care for & breed, so geneticists can see results of experiments quite quickly.

  16. tanwi

    Drosophila melanogaster
    these are easy to care for, breeds quickly, and lays many eggs

  17. Dibyo

    fruit fly, or drosophilia – is a model creature in biological experiments

  18. Rogi

    friut fly.
    Ppular with researchers due to it’s genetic code being relatively similar to ours. Plus, they’re cheap and easy to maintain.

  19. Teju

    Fruit fly – Its genetics research made evolution and Darwins theory more credible.. They have one of the biggest chromosomes known yet..
