A lizard with a striped tail and a normal head is crossed with one having a normal tail and a spotted head, producing normal looking (no stripes or spots) lizard progeny. What phenotypes would be expected to be produced by mating these progeny with each other, if the genes conferring stripes and spots were on different chromosomes? (Hint: alleles for striped tail and spotted head are recessive)

Suppose there were 1000 police employed in New York at the time of 9/11, and suppose that 70% of police participated in 9/11 rescue efforts.  This is shown with the values already given in the table.   Of those who participated in rescue efforts, 25% later developed moderate to severe alcohol problems.  Of those who did not participate in rescue efforts, 80% did not develop alcohol problems.  Using this information, Find the missing values within the table. Determine the probability that a police officer had moderate to severe alcohol problems given that they participated in the 9/11 Rescue.   Police officers helping with 9/11 Rescue and Possible Alcohol Problems No Alcohol Problems Moderate to Severe Alcohol Problems Total Participated in 9/11 Rescue 700 Did Not participate in 9/11 Rescue 300 Total 1000   What is the probability that a police officer had moderate to severe alcohol problems given that they participated in the 9/11 Rescue?   Submit your work on your free response paper.
