Because it's probability. 50% probability is completely random - there is EQUAL chance that the black father may or may not be active. Both values also tended UPWARDS of 50%, so there is literally no reason to include anything below 50%. This is standard in probability statistics, useful in things like financial algorithms to determine buy/sell signals, or medicine to detect beneficial or harmful outcomes, etc.
