    Text Box: Barless to  Bar Text Box: Parents markings

Text Box: Parent No 1 - Barless Cock or Hen (Sex doesn’t matter) and being Barless the hidden  pattern gene is also Barless - I have also shown the genetic symbol

Text Box: Parent No 2 - Opposite sex to parent No 1 and in this case a barred pigeon carrying barless

Text Box: Percentage split of youngsters produced

Text Box: Offspring produced in this case 50% Bars Carrying barless and 50% barless

Text Box: Notice the other mating has produced 100% Bars carrying barless that’s because one of ther parents was a pure bar ie: Bar carrying bar
