Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for genetics and developmental biology. The study of its embryogenesis unlocked the century-long puzzle of how development was controlled, creating the field of evolutionary developmental biology . [ 1 ]
Their life cycle is broken down into four stages: embryo, larva, pupa, adult. [30] The eggs, which are about 0.5 mm long, hatch after 12–15 hours (at 25 °C or 77 °F). [ 25 ] [ 26 ] The resulting larvae grow for about four days (at 25 °C) while molting twice (into second- and third-instar larvae), at about 24 and 48 hours after hatching.
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.
Drosophila circadian rhythm is a daily 24-hour cycle of rest and activity in the fruit flies of the genus Drosophila. The biological process was discovered and is best understood in the species Drosophila melanogaster. Many behaviors are under circadian control including eclosion, locomotor activity, feeding, and mating.
Drosophila sex-chromosomes Human male XY chromosomes after G-banding Main article: XY sex-determination system The XX/XY sex-determination system is the most familiar, as it is found in humans.
Drosophila virilis is a species of fruit fly with a worldwide distribution (probably due to human movements [1]), and was one of 12 fruit fly genomes sequenced for a large comparative study. [2] The males have bright red gonads that can be seen through the cuticle.
The best known species of the Drosophilidae is Drosophila melanogaster, within the genus Drosophila, also called the "fruit fly." Drosophila melanogaster is used extensively for studies concerning genetics, development, physiology, ecology and behaviour. Many fundamental biological mechanisms were discovered first in D. melanogaster. [2]
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
