For the first set, we have the probability of $AA = \frac{1 + 1/2}{2} = \frac{3}{4}$. The second set of parents are the following: $AA = 1$, $Aa=2/3$, and $AA = 1/3$. How to read a pedigree Transmission probabilities Lod scores Thanks to Mary Kuhner for most slides. Then, the probability that she will not pass it to either of two offspring is (1/2) (1/2) = 0.52 = 1/4. Probabilities in pedigrees are calculated using knowledge of Mendelian inheritance and the same basic methods as are used in other fields. The first formula is the product rule: the joint probability of two independent events is the product of their individual probabilities; this is the probability of one event AND another event occurring.

For example, Charpentier et al. Pedigree analysis Doctors can use a pedigree analysis chart to show how genetic disorders are inherited in a family. Calculating probabilities in pedigrees of X-linked conditions where A and B are rare recessive conditions. Once the mode of inheritance of a disease or trait is identified, some inferences about the genotype of individuals in a pedigree can be made, based on their phenotypes and where they appear in the family tree. Assume individuals outside the family are not carriers of r unless there is evidence. The answer in the book is 2/35.

Female III-4 is pregnant via male III-5. For question 1, the following are required for IV-3 to have condition A (aa): -II-5 has the genotype Aa (probability = 2/3). 4 possibilities, however, because aa is lethal and we're specifically being asked about carriers*, this reduces the probability to 3 possible genotypes. All of these requirements are needed in sequence, so you apply the Using what youve learned about Mendelian genetics and X-linked inheritance, you can infer and predict a surprising amount of information from relatively few clues.
