How color blindness is inherited

Color blindness affects approximately every 1 in 12 men (8%) and 1 in 200 women (0.5%). This means there is definitely one in your neighborhood or school class affected by it. Most of them are male, because the most common form called red-green color blindness (a term which is also misleading) is encoded on the x-chromosome and therefore sex-linked. The term red-green color blindness is often used but actually not quite correct. Every type of color vision deficiency affects the whole color spectrum and therefore can not be reduced to just certain colors. Of course, for the most often encountered types Protanomly (the milder form or red-weakness) or Protanopia (missing red cones, red-blindness) and Deuteranomaly (green-weakness) or Deuteranopia (green-blindness) the colors red and green are the most problematic and misinterpreted or indistinguishable ones. But people suffering from any of those forms have issues with the red or green part in every color, so the whole spectrum of colors is affected. Besides red-green color blindness, which is encoded on the x-chromosome (sex-linked) and therefore much more common for men, there are also forms of color vision deficiency which are evenly distributed between male and female like Tritanomaly (blue-weakness) or Tritanopia (blue-blindness) and the real color blindness Achromatopsia (monochromacy) or the so called blue-cone monochromacy (only blue cones). #genetics #ColorBlindness #redgreenColorBlindness #visionDeficiency #sexlinked #NikolaysGeneticsLessons #RedGreenColorBlindness #geneticDisorder #mutation #geneticDisease #xchromosome #recessiveGeneticDisorder #Hemophilia #physiology #biology #ColorBlindnessDiseaseOrMedicalCondition #HealthIndustry #GeneticsFieldOfStudy #Xlinked #achromatopsia #GeneticsExamQuestionsSolutions #ColorVisionDeficiency #GeneticsLecture
