Apedigree chart can show a trait that is: dominant, a mutation, both dominant and a mutation

Answer;

both dominant and a mutation

Explanation;Pedigree charts shows inheritance of a certain trait over generations. A pedigree can therefore track an inherited trait through several generation. A dominant trait is an inherited trait that appears in an offspring if it is obtained from a parent through a dominant allele. Such a trait is seen when heterozygous genotype is present. If a trait is dominant, then its appearance on a pedigree chart will be such that it appears in every single generation.Mutation refers to sudden spontaneous changes that occurs randomly in the genome of an organism. Mutations may also be observed in a pedigree chart.
