The following pedigree shows what type of inheritance?
In the following pedigree, is the disorder’s mode of inheritanceautosomal dominant, autosomal recessive, or X-linked recessive?Explain your reasoning.
What is the most likely pattern of inheritance for this disorder? (Is it autosomal dominant? Autosomal recessive? X-linked dominant? X-linked recessive? Y-linked? Mitochondrial?) Please include two specific pieces of evidence, present within the pedigree, that indicate that this pattern is most likely, as opposed to any other potential pattern. You may assume that the gene responsible for the trait is fully penetrant.
