7. Research a mutation found on the X chromosome, determine whether it is X-linked dominant or X-linked recessive, and consider how the probability of passing on the trait
changes depending on the sex of the carrier and the sex of the carrier's offspring (for
example, investigate an X-linked mutation like Rett syndrome and determine how being X-
linked dominant affects the ability to pass the condition on to female and male offspring).

Darwin’s hypothesis about how life changes over time is now called?

Ms. w, a 21-year-old woman, came into a clinic after suffering a deep laceration on her foot while walking barefoot around her yard. the wound was cleaned, sutured, and bandaged, and she was released to return home after receiving tetanus antitoxoid. within 72 hours, the wound area was red and swollen, the suture line was dark in color, and it was accompanied by severe throbbing pain. ms. w had a high fever, her heart felt like it was racing, and she was finding it hard to concentraten even on simple tasks. she returned to the clinic and was immediately taken to the hospital. following lab tests, a diagnosis of acute necrotizing fasciitis was made. discussion questions 1. explain why ms. w. received a tetanus antitoxoid before leaving the hospital. (see chapters 3 and 4, infection and passive immunity.) 2. explain how acute necrotizing fasciitis developed in this case and the pathophysiology involved. (see acute necrotizing fasciitis.) 3. what is the potential outcome for ms. w if antibiotic drugs do not reduce the infection quickly?

Which claim correctly describes how genes can produce a phenotype? one gene is responsible for all traits. each trait is determined by a single gene. one gene can be responsible for many traits. each gene is responsible for exactly one trait.
