What? A pedigree with genotypes is shown below. Three individuals with a particular trait have their pedigree symbols shaded. Your task is to report 1) what type of inheritance pattern this is (dominant or recessive)? and 2) all of the possible alleles that are linked to (could be causing) this trait. Make sure to double-check your work: ensure that the inheritance pattern (from part 1) is consistent with all of the genotypes in the pedigree (from part 2).

Step 1
This indicates that the trait is present in these individuals. - The individuals with the trait are (CG)_(2), (CG)_(3), and (CG)_(4). - Since the trait is present in individuals with both homozygous and heterozygous genotypes, this suggests a dominant inheritance Show more…

A pedigree is shown below for a common dimorphism with full penetrance and expressivity. Please fill in the correct genotypes on the lines shown in the pedigree. The lines are below the person for which you need to provide a genotype. Use gene symbols A and a. If an allele can not be determined, use a dash (-). If a genotype is highly likely for (an) individual(s), show the highly likely genotype(s) and explain your reasoning. It is recommended that you print extra copies to work with and then upload the clean, final copy. This way you can work through the problem with care and the grader will not be confused by your gene symbols.

Pedigree Charts Studying pedigree charts can help you determine the mode of inheritance of a trait and can also help you identify genotypes of individuals. The following symbols are used: affected female unaffected female affected male unaffected male Step 1. The way your thumbs rest on each other when your fingers are interlaced (you are holding your own hands) is inherited. Your right thumb resting over your left thumb is a recessive trait. The following is a sample pedigree for a family affected with recessive interlacing. Write the genotypes for each of the family members in the red box next to their symbol (A is dominant and a is recessive) (11 points).

Draw a three generation pedigree in which affected individuals are filled symbols and unaffected individuals are open symbols that clearly exhibits X-linked recessive inheritance. You may not indicate any genotypes on the pedigree. The pedigree must exhibit all of the hallmarks of this type of inheritance and should not be able to be explained by any other type of inheritance.
