Does having parents with broad ancestry across europe cause more phenotype variation among full siblings? For example, if you take a welsh mother and a welsh father, their kids would all have welsh phenotypes. But if you take a welsh mother and a polish father, then their kids should have welsh or polish phenotypes, and mixes between the two. Is this seen within people of mixed European descent? Will children born to "euromutts" have more variation from each other? Let's take Old Stock U.S.A. which is a blend of northwest euro, centered heavily on the British Isles. The population of these people, then, should vary between all the phenotypes originally contained within their founding populations. Would full siblings between people in these populations have phenotypes ranging between all the types of europeans the population was composed of?
