Pigeon Genetics: Color, Pattern and Modifiers / Cross-Breeding Technique

What do hemophiliac human males have in common with dilute hen pigeons? Both are the result of a sex-linked recessive trait that works similarly but opposite in both species humans (XY sex determination system) and pigeons (ZW sex determination system).

Go over basic genetics (color, pattern and modifiers) to better understand how the cross-breeding technique works with the use of simple Punnett squares
