Question

Animal breeding question  

Appalachian soldier snakes come in three colors that are determined by a single locus (C) such

          that:

                CC => army drab

                Cc => camouflage

                Cc => navy blue

         These snakes also come in three skin textures that are also determined by a single locus (T) such

         that:

                TT => Rough

                Tt => Smooth

                tt => downright slimy

If two down right slimy army drab soldier snakes mate, producing 67 offspring, how many baby snakes do you expect to be downright slimy army drab? Will exactly this number be downright slimy army drab?

  Here is my answer.        ttCC x ttCC

If the above mating produces 67 offsrping, all offspring would be downright slimy and army drab, as those are the only two alleles each parent has to offer. For this particular mating, this should hold true each time.

Does this look correct?

Explanation / Answer

You are correct.

Genotype of parents: CCtt x CCtt
