However, all her sons will have the trait of the disorder, and her daughters (assuming her husband has the normal genotype) will either be carriers or homozygous for the normal allele (Fig. Regardless of their level of detail, pedigrees highlight who is affected by the disorder in question and who is not.

Here is a simple experiment on how to prepare and analyse the pedigree charts. Looking at the youngest generation (generations are often labelled, with the oldest generation being I, their descendants being II, and the youngest being III), we can see there is a male child who is affected by galactosemia.

By using common sense and some fundamental principles, we can analyze pedigrees for just about any trait - from black hair color to osteogenesis imperfecta to dimples. Also Read: Genetic disorders. In fact, the preponderance of disorders that primarily affect men is typically due to the presence of a single X-chromosome, such that whatever disordered trait is on that chromosome cannot be masked by the normal trait that would be on a paired X-chromosome in females. Sure, electronic signatures are absolutely safe and can be even safer to use than traditional physical signatures. There are five basic modes of inheritance for single-gene diseases: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and mitochondrial.

Because it is exclusively seen in males, we can safely presume the disorder is X-linked recessive.
