**Comments upon:**

The edged colour variety inherits recessive. This means that hen and cock can be both split. The best combination: cock 1 x hen 1, both edged. The mating of a strong edged cock with a weak edged hen is obvious.

The next best combination is the combination cock 1 x hen 2 and cock 2 x hen 1. Here we find in the cross-table edged and splits.

Some remarks have to be made.

On the average more edged cocks then edged hens are born. This phenomenon is named: predominance. The ratio cocks: hens is about 4:1.

This counts especially for the strong edged Bourke’s.

According to the recessive inheritance, about 50% of the young of the combinations :cock 1 x hen 2 and cock 2 x hen 1 should be edged. But this percentage is much lower.

So the edged does not follow the rules. Maybe there are two recessive factors responsible for the edged colour variety . At this moment there is no better cross-table then presented here.

More information is presented in the case study for the early development of the edged.
