A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. The output from an LED can range from red (at a wavelength of approximately 700 nanometers) to blue-violet (about 400 nanometers). Some LEDs emit infrared (IR) energy (830 nanometers or longer); such a device is known as an infrared-emitting diode (IRED). read less

Cystic Fibrosis is the most common generic disease in white european and american populations.It results from one of a nmber of mutations in a single gene that codes for a protien involved in the transport of salts in the cells of the body. The cystic fibrosis gene is described as recessive , which means that individuals with only one copy of the gene so called carriers , show no symptoms of the disease and manny be unaware that they carry the gene. Individuals with two copies of the faculty CF gene will show symptom of the condition. Among white europeons,the probability of being a carrier is 1/25. For a child whose parents are both carriers, the probability of inheriting a copy of the CF gene from both parents is 1/4. a)What is the probability that any two white Europeans planning to have a child together would both be carriers? b) What is the probability of the child having cystic fibrosis?
a) Probability of any two white Europeans planning to have a child together would both be carriers = (1/25) (1/25) = 1/ 625 b) Probability of the child having cystic fibrosis = (1/625) (1/4) = 1/2500
