Most errors were caused by not following the working rules
  OR not reading the problem carefully.  If you do not learn 
  to do these fundamental study and test strategies, there is 
  not much I, a study partner or a tutor can do for you.
  All of these problems had been addressed in class and 
  on the web.

Problem 1   List gametes made by individual who is 
      EITHER (depending on which test)
          (RK)(RK)FfXX   -  (RK)FX      AND      (RK)fX

          (RG)(RG)EeXX  -   (RG)EX      AND      (RG)eX

          (RK)(RK)FFXY  -   (RK)FX      AND      (RK)FY


Prob. 2  This was a standard dihybrid cross.
             Original parents were homozygous dominant for one trait 
             and recessive for the other.  Each parent could produce only 
             one kind of gamete so the F1 had to be heterozygous for 
             both traits and dominant for both.  You had to write the letters
             for the genotype and the descriptive terms for the phenotype.

             The F2 yields:         9 double dominant:
                                    3 dom, recessive:
                                    3 recessive, dom.:
                                    1 double rec.
                 You had to give the traits as well as the numbers! 


Prob. 3   The male was heterozygous for each trait.
              Not a sex-linked problem.

Prob. 4   As stated, a sex-linked problem and a recessive condition.
              The female was a carrier (X with capital letter as superscript, and 
                  X with lowcase letter as superscript)
              Her husband was normal and, as a male, has only one X
                  (with capital letter as superscript)
               The son named was hemophilic so had to have lowcase
                   superscript on his single X
              Since the couple each have an X with the normal allele,
                   a non-carrier daughter is quite possible.
