Isso é quase certamente The Cuckoo's Boys de Robert Reed publicado pela primeira vez em 1998 De acordo com esta resposta :
In the near-future title story, a lonely genius clones himself -- not once, but millions of times -- by creating a virus that affects pregnant women. Throughout the world, women give birth to baby boys with the genetics of Phillip Stevens. Then a few years later, a man with a mysterious past becomes a mentor to three of these clones -- and as their teacher, he tests and challenges them. Are these boys little more than genetic copies of Stevens? Or are they distinct individuals, with unique personalities and coming-of-age problems?
