In the 1950’s, and the 1960’s the biologist Edgar Zwilling experimented on chicken embryos by cutting small pieces off of the bird, and either keeping them removed, or moving the piece to another part of the embryo. One experiment took off the tip of the embryos developing wing, which completely stopped the wing from forming. This discovery was the discovery of the ZPA, which led to the discovery of the hedgehog gene, which allowed scientists to discover the gene in all developing animals. 2. The Hedgehog gene is a gene found in the center of flies. It was named the Hedgehog gene due to its resemblance to a hedgehog, and is used to determine which side will be the front of the fly, and which side will be the back of the…

    The scientists Tabin, McMahon, and Ingham found the gene in flies that made one end of a body segment look different from another, they called it hedgehog. The mammal equivalent is called Sonic Hedgehog. Sonic Hedgehog is present in a variety of different species.

  • Supersonic Research Paper

    of a problem when flying below the sound barrier. When the sound barrier is broken, then a lot changes and the aircraft needs to be as streamlined to do that. To make an engine more streamlined it becomes smaller and more part of the wing of the plane. The engine might be smaller but it has to move more air than a subsonic engine which means the rate at which the engine rotates will be higher, increasing the noise. With hearing protection this might not be a huge deal, but for people who…

    They later found a control panel for the chicks limbs, and if altered, the limb development would slow and accelerate. Deformities in the digits occurred when the tissue was removed later, and undergrowth occurred when removed early. This was an extremely important finding because they found out that this was occurring because one single gene, and this was the discovery of the Sonic Hedgehog Gene. The Sonic Hedgehog Gene, was initially found in fruit flies as something that told other cells…
