Creating a pedigree chart from a family history and hypothesizing pattern of inheritance A family with a new disease caused by a mutant gene has been found. The family history has been collected and recorded. You will now create a pedigree chart from their family history and use the pedigree to predict the pattern of inheritance the disease follows. • Read the following family history: Patient 1 and Patient 2 visited a genetics counselor and provided their family histories. As...
Procedure 8.5 PEDIGREE CHARTS Pedigree charts are diagrams that illustrate how a trait is inherited through generations of a family. They can help us determine genotypes and patterns of inheritance for a trait. HOW TO READ A PEDIGREE CHART 1. Look at the sample pedigree chart in Figure 8.7. 2. Square boxes represent males and circles represent females. 3. A filled-in figure means that the trait is present in that individual. An empty figure means the trait is not present....

Use the pedigree shown below to answer the following questions. The pedigree is for a family in which dark-shaded symbols represent individuals with a hereditary form of early-onset colon cancer. Numbers under the symbols are the individual's age at the time of diagnosis. Crossed through symbols means the person is deceased. A) What is the genotype of the deceased individual in generation II? B) From this pedigree, how does this trait seem to be inherited? C) What are the possible...
A family tree of sorts is called a pedigree. The symbols used for a pedigree are: O female, unaffected Siblings are placed in birth order from left to right and are labeled with Arabic numerals. Each generation is labeled with a Roman numeral.

Styles 6. Insert a picture of your pedigree chart for this family with genotypes filled in here. 7. Which pattern of inheritance do you think the disease shows? Explain your reasoning. 8. Patient 1 and Patient 2 in the pedigree chart would like to know what the chances are that they will have a child with the disease. What do you tell them? Use a Punnett Square to show your work.

II Review a tla + This pedigree shows the inheritance pattern of a recessive maternal effect gene in Drosophila. In maternal effect, the offspring's phenotype is under the control of nuclear gene products present in the mother's egg. In this example, the presence of the a + allele in the mother is required for proper wing development in the offspring. a tla a/a In the pedigree, individuals who are wingless are indicated by a shaded symbol. The phenotypes and genotypes...

. O . Using Pedigrees to hypothesize patterns of inheritance 5. For each of the pedigree charts on the following page, determine which pattern of inheritance most likely explains the observed pattern of traits in the family shown. Observe the general patterns in the pedigree charts on the following page o males vs females? parents with disease? Compare these patterns with the clues on the previous page to hypothesize a pattern of inheritance Based on this pattern of inheritance, use...
