Aman employed for several years in a fire extinguisher assembly factory becomes the father of a hemophiliac boy. there is no hemophilia in the pedigrees of the man’s ancestors and his wife’s ancestors. another man, also employed for several years in the same assembly factory, has an achondroplastic dwarf child. there is no achondroplasia in the pedigrees of the man’s ancestors and his wife’s ancestors. both men sue their employer for damages claiming that high levels of pfas chemicals in their workplace caused mutations in their germlines. as a geneticist, you are asked to testify in court. what do you say about each situation? does either plaintiff have a case? (note: hemophilia is an x-linked recessive; achondroplasia is an autosomal dominant.)
