The birth of one child does not influence the chance of the next child being normal, a carrier or affected. As you probably see from the above example, a child with 2 parents who have autosomal recessive retinitis pigmentosa has a 100 % chance of getting the disease. http://www.geocities.com/retinitis_pigmentosa_rp/r_pigmentosa_autorecess.html   (972 words)      Genetics Tutorial Furthermore, if one needs two changed genes (one from the mother and one from the father) to express a condition, the condition is said to be inherited in a recessive manner. If one needs only one changed gene to express a condition, the condition is said to be inherited in a dominant manner. When one counsels such families, there is a very low chance that a second child with the condition will be born. http://www.hopkinsmedicine.org/greenbergcenter/tutorial.htm   (1288 words)      Dominant gene - Wikipedia, the free encyclopedia Dominant traits have a 50% chance to pass from parent to child. This example demonstrates that one can only refer to dominance/recessiveness with respect to individual phenotypes. If a genetic trait is dominant, a person only needs to inherit one copy of the gene for the trait to be expressed. http://en.wikipedia.org/wiki/Dominant_gene   (217 words)      Polycystic Kidney Disease People with autosomal dominant PKD should see a doctor if they have severe or recurring headaches—even before considering over-the-counter pain medications.
