?Sex Limited Inheritance in Drosophila? (1910), by Thomas Hunt Morgan
نویسنده
چکیده
In 1910, Thomas Hunt Morgan [4] performed an experiment at Columbia University [5], in New York City, New York, that helped identify the role chromosomes play in heredity. That year, Morgan was breeding Drosophila [6], or fruit flies. After observing thousands of fruit fly offspring with red eyes, he obtained one that had white eyes. Morgan began breeding the white-eyed mutant fly and found that in one generation of flies, the trait was only present in males. Through more breeding analysis, Morgan found that the genetic factor controlling eye color in the flies was on the same chromosome that determined sex. That result indicated that eye color and sex were both tied to chromosomes and helped Morgan and colleagues establish that chromosomes carry the genes [7] that allow offspring to inherit traits from their parents.

Alfred Henry Sturtevant (1891?1970)
Alfred Henry Sturtevant studied heredity in fruit flies in the US throughout the twentieth century. From 1910 to 1928, Sturtevant worked in Thomas Hunt Morgan?s research lab in New York City, New York. Sturtevant, Morgan, and other researchers established that chromosomes play a role in the inheritance of traits. In 1913, as an undergraduate, Sturtevant created one of the earliest genetic maps ...
متن کامل2010: A century of Drosophila genetics through the prism of the white gene.
In January 1910, a century ago, Thomas Hunt Morgan discovered his first Drosophila mutant, a white-eyed male (Morgan 1910). Morgan named the mutant gene white and soon demonstrated that it resided on the X chromosome. This was the first localization of a specific gene to a particular chromosome. Thus began Drosophila experimental genetics. The story of the initial work on white is well known bu...

In 1913, Alfred Henry Sturtevant published the results of experiments in which he showed how genes [4] are arranged along a chromosome. Sturtevant performed those experiments as an undergraduate at Columbia University [5], in New York, New York, under the guidance of Nobel laureate Thomas Hunt Morgan [6]. Sturtevant studied heredity using Drosophila [7], the common fruit fly. In his experiments...

IN the early 1910s, researchers at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, might have wondered why a colleague, Thomas Hunt Morgan (Figure 1), began shipping fruit flies from his Columbia University lab to the MBL each summer. After all, the Woods Hole currents supplied the MBL with a rich variety of marine organisms and Morgan, an avid practitioner of experimental ...

Drosophila melanogaster, the common fruit fly, has been used as a model organism in both medical and scientific research for over a century. Work by Thomas Hunt Morgan (1866–1945) and his students at Columbia University at the beginning of the twentieth century led to great discoveries such as sex-linked inheritance and that ionising radiation causes mutations in genes. However, the use of Dros...
