What is the prevalence of the trait or disorder? What are the main genetic factors? s the genetic cause of this disorder or trait known? What gene(s) have been proven to be involved? Or, if not known, what genes are thought to be involved? Is it caused by a single gene? polygenic? Multifactorial? Devote a few paragraphs to this This could be one of the longest parts of the paper, if you choose to focus on this. If multiple genes are thought to be involved, discuss the specific role of at least one of them in depth (if known). Is the gene you’re discussing thought to play a major or a minor role in the phenotype? What chromosome is it on? What protein does it code for, and how might the protein possibly contribute to the phenotype? If no genes have yet been identified, indicate this, and devote at least one paragraph to any current efforts to determine which…Illustrate the Mapping the gene for Huntington disease ?
