That Mercx jr never outshone Mercx sr is hardly surprising. It is an example of the well-observed phenomenem of "return to the mean"

If a couple of great athletes or super-good-looking models chose to procreate with each other, then their offspring will be more athletic/pretier than average, but rarely more than their parents, who are on the very extreme of the normal distribution.

patriot: Genetics is something that happens in populations, not individuals. A gene/trait will be more common in a population if it results in better reproductive success. That may be because it provides a benefit within a certain environment (eg high altitude living). If you remove that environmental pressure, then over time (many generations) you would expect that gene to be less useful, less fit, and hence less frequent within the population .
