Gene that the media described as the "bad hair day" gene is technically called frizzled (OMIM 601723), named for its well-studied counterparts in fruit flies and mice. Frizzled is inherited as an autosomal recessive trait, and the gene is on chromosome 2. A gene for "strikingly red hair," also autosomal recessive, is on chromosome 4 (OMIM 266300). Gina Rollins and Spencer Davis have boring, straight brown hair. They are amazed to discover that each has a mother (Inga and Magda) with strikingly red, frizzled hair. Their fathers, Ralph and Fred, both have boring, straight brown hair. If Gina and Spencer have children, what is the probability that each will have either trait, both traits, or neither?
