  I have been given a problem to do with crosses and stuff. I have done it but i got a weird answer so I wonder if you could help me:
  C – coloured feathers
  I – blocks expression of C
  c – white feathers
  i – dosent block C
  Leghorn chicken – CCII
  Wyandotte – ccii
  Qn – What propotion of the F2 progeny obtained from crossing those two above will have white feathers?
  My answer – 13:3
  Am I correct? What do you get?
