When you cross an Angolan Python to a Ball Python, the offspring (Angolan Balls) all have 50% of their genetic makeup from the Angolan Python and 50% of their genetic makeup from the Ball Python.

When you cross an Angolan Ball to a Ball Python, the offspring will have varying genetic makeups...
At one extreme they would be 50% Angolan Python 50% Ball Python.
At the other extreme they would be 100% Ball Python.
The likelihood of either of these extremes occurring would be extremely small.
The most common outcome would be animals that were either 25% Angolan Python 75% Ball Python or something very close to these ratios.

While I completely understand the point you made regarding chimps, I fail to see the relevance with regard to this subject. The issue is not simply how genetic material is inherited in a hybridization, it is how genetic material is inherited in any breeding.

Diploid organisms inherit half of their genetic makeup from each parent. Each parent does not pass along it's entire genetic makeup, but instead passes along half of its genetic makeup. Although the genetic makeup passed to each offspring is consistent in quantity, it is not consistent in content. If parents always passed identical sets of genes to their children, all of their children would be identical.

The Angolan Ball will always pass its half of the genetic makeup to the offspring. Although the "quantity" of this material is constant, the "content" is not.

It's really not a huge deal to me whether folks disagree with our perpective, whether they are open to our perspective, or whether they agree with our perspective. I certainly have no problem "agreeing to disagree".
