I.  When 2 pure breeding parental plants were crossed, one red and one
pink, all the offspring (F1) were blue.  When 2 of the blue (F1) were
crossed with each other, 1/4 of THEIR (F2) offspring were pink and 1/16
of their F2 offspring were pure breeding for blue.

A.  Give the GENOTYPE of the pure breeding red parental plant starting
with the first letter of the alphabet and using as many additional
letters as are MINIMALLY required.  Use (a) capital letter(s) to
represent (the) dominant allele(s).  The trait of flower color in this
example is autosomal.

B.  If 2 red F2 were chosen at random and mated to each other, what
fraction of THEIR offspring would be pink?

If anyone know how to do this prob., pls reply ASAP...THANKS LOTS in
advance!!
