Another question is, are there plausible rules of heredity and reproduction that would alter the Boy/Girl ratio if "families" ceased reproducing at the first boy, but not if they stopped randomly?
Suppose different couples have different chances of having a boy. For example, half the couples have a 75% chance that each of their children is a boy, while half the couples have a 25% chance that each of their children is a boy. Now a "stop at the first boy" rule will change the ratio in the population. Andy
