Sex-Linked Inheritance Problem Set Problem 7: Red-green color blindness in humans Tutorial to help answer the question A human female "carrier" who is heterozygous for the recessive, sex-linked trait causing red-green color blindness (or alternatively, hemophilia), marries a normal male. What proportion of their male progeny will have red-green color blindness (or alternatively, will be hemophiliac)? Tutorial Genotypes and phenotypes of parents The eggs of the mother will contain either a normal X chromosome or an X chromosome with the mutation causing red-green color blindness. The sperm of the father will contain either the normal X chromosome or the Y chromosome. Genotypes and phenotypes of offspring None of the female children would be red-green color blind, but half would be "carriers." Half of the sons would inherit the allele from their mother and be afflicted.

Color Blindness Problem Set This problem set is based on a question received from a woman named Audrei. Audrei is red-green color blind and so are other members of her family. She wanted to know if we could help her understand how she inherited her color blindness. Audrei's family There are 7 children in Audrei's family, three girls and four boys. Two of the girls, Audrei and Liz, are red-green color blind. Caroline has normal color vision. Only two of the boys have been tested. Paul is color blind and David has normal color perception. Andrew and Jason, who have not been tested, may or may not have normal color perception. Barbara, the mother of the seven children, has normal color vision, but Sidney, the father, has the red-green color perception defect. Audrei also has a half brother Stephan. Audrei and Stephen have the same mother, but a different father. Stephan is also red green color blind. Red-green color blindness Red-green color blindness is an X-linked, recessive trait. In this problem set we will establish the pedigree of Audrei's family and see how the color perception defect is passed on from one generation to the next, but first let's look at a brief introduction to sex-linked inheritance. For more complete information about sex-linked inheritance review the Sex-linked Inheritance Problem Set in the Mendelian Genetics section.

Antibiotics could provide a cheap, safe and effective way of wiping out the disease, which is caused by a parasitic worm. Scientists from the United Kingdom, Cameroon and Germany, say their experiments show that using antibiotics to kill bacteria living on the parasite, also kills the parasite itself. This is an important step in finding a cheap, safe and effective way of curing the infection Professor Alexander Trees, Liverpool School of Tropical Medicine River blindness, or Onchocerciasis, causes severe itching, disfiguring lesions and lesions of the eye that can cause blindness. It is most prevalent in sub-Saharan Africa, though the World Health Organisation says it will have stamped out the disease in West Africa by 2002.

Home Products Projects Research Demos Contact 1 in 12 people suffer from some sort of color deficiency CBC: Color Blindness Check For this little tool we got our inspiration from Cal Henderson , who made a page showing the effects several types of color blindness can have on the readability of a website. We thought Cal did a nice job and since we are doing two projects where accessability for people with a disablility is a major issue, we thought we might add a little of our own to his work. CBC is a little tool we made for people to test their webpages with. It re-colorizes any webpage you like into a palette that closely resembles the typical palette available to a person having a red/green color vision deficiency. (This is the most common color blindness. Comparing Cal Henderson's data, it comes closest to Protanopia.) Below we describe two ways to use CBC. Both require Internet Explorer 5.0 or more on a Windows PC. There is some chance that even then CBC will not work... in that case you need to install the latest DirectX drivers.

Color Blindness Although defective color vision may be acquired as a result of another eye disorder, the vast majority of color blind cases are hereditary - present at birth. Color blindness is rooted in the chromosomal differences between males and females. Females may be carriers of color blindness, but males are more commonly affected. About 8 percent of males and 0.5 percent of females are color deficient. Color blindness is a malfunction of the retina, which converts light energy into electircal energy that is then transmitted to the brain. This conversion is accomplished by two types of photoreceptor cells in the retina: rods and cones. The cones are responsible for encoding color. Each cone contains structures or visual pigments sensitive to one of three wavelengths of light: red, green, and blue. Normal persons are able to match all colors of the spectrum by mixtures of only three fundamental color sensitivities. Hence, the huge variety of colors we perceive stems from the cone cells' response to different compositions of wavelengths of light. Defects in color vision occur when one of the three cone cell color coding structures fails to function properly. One of the visual pigments may be present and functioning abnormally, or it may be absent altogether.

E - Mail Me The eye and a camera have a lot in common. They both have compound lenses. To focus a camera you move the lens backward or forward. The eye is focused by the ciliary muscle witch stretches the lens, changing its shape. The iris, just like the aperture in a camera, controls the amount of light that enters the eye. The aperture in a camera protects the film from over exposure. The iris in the eye protects the sensitive retina from light damage. The retina is like the film in a camera, covering the back of the eye. It contains millions of photoreceptor cells. These cells convert light rays into electrical signals that are sent to the brain through the optic nerve. The signals from both eyes are combined and converted into sight by the brain.

Motion Induced Blindness Yoram Bonneh, Alexander Cooperman and Dov Sagi October 2000 Last Updated: June 2001. Motion Induced Blindness (MIB) is a phenomenon of "visual disappearance" in which salient visual stimuli disappear as if erased in front of the observers eyes. This demo demonstrates several properties of this phenomenon. It is implemented as a set of GIF animation and can only be appreciated if the apparent motion appears smooth or almost smooth. In general, fixate in the center or lower part of the screen without moving the eyes, pay attention to the moving pattern and observe what happens to the static yellow dots. For better results, download an executable version of the demo, available for Linux x86 and Windows systems. The demo is best perceived in the dark.

Color blindness From Wikipedia, the free encyclopedia. Color blindness is the inability to perceive differences between some or all colors that other people can distinguish. It is most often of genetic nature, but might also occur because of eye nerve or brain damage or due to use of some chemical substances . The English chemist John Dalton in published the first scientific paper on the subject, "Extraordinary facts relating to the vision of colours," after the realization of his own color blindness. Table of contents 1 Rates of occurrence 2 Retinal origins of color blindness 3 Red-green color blindness 3.1 Types of red-green color blindness ... edit Rates of occurrence While exact numbers vary in various populations, color blindness affects a significant proportion of people. Amongst Americans, approximately 10% of males suffer from some form of color perception deficiency. Isolated communities with a restricted gene pool sometimes produce high proportions of color blindness, including the less usual types: examples include rural Finland and some of the Scottish islands.

FCGCF provides diagnostic screenings opportunities for high risk glaucoma population groups in their home districts across the nation. In support of the 77 members and former members of the Congressional Glaucoma Caucus, FCGCF arranges and provides screenings for glaucoma and other eye diseases throughout the United States at no cost to screening participants. From April 2001 to March 2004 we have screened approximately 23,500 individuals and have held over 640 screenings nationwide. Of those screened, approximately 34% were referred for further vision related medical treatment, and of those referred, 16% displayed signs consistent with glaucoma. It is well known that for the vast majority of individuals with glaucoma, the chances of preserving their sight is significantly improved if diagnosed and treated early enough. FCGCF targets groups of people at high risk of developing glaucoma or other eye disease, such as African Americans and Hispanics over the age of 40. We also target geographic areas, where adequate eye care is unavailable. FCGCF utilizes mobile facilities, complete with the most up-to-date screning equipment, so that we can travel to high risk areas.
