Indeed. It can't even be a case of parthenogenesis, were such possible in humans, because the offspring was male, meaning (according to the story, but not to the ordinary listener in the bar) Jesus got his Y-chromosome from God.
Of course, Mark's earlier version has the great advantage of being the only vaguely credible version. His Jesus isn't born of a virgin, but is an ordinary Jewish male who, when JtB baptizes him, is then and not before adopted by God as [his] son, in the same manner that God had adopted David as [his] son (Psalm 2:7) ─ a view expressly confirmed in Acts 13:33.
Oddly enough, neither Paul nor the author of John had heard of that virgin-birth story, or they'd have been grossly remiss not to mention it. Instead, the Jesus of Paul and the Jesus of John (unlike the synoptic Jesuses, and on a Gnostic model) lived in heaven with God, created the material world (regardless of what Genesis might say) and came to earth as God's envoy ─ but with zero details about how that coming to earth was accomplished. However, we might infer those Jesuses were born of Jewish parents, since both authors claim their Jesus is descended from David.
(Mark's Jesus, you'll recall, is the only one who says out loud that you don't need to be descended from David, and the absurd and irreconcilable 'genealogies' purporting to show Jesus' descent from David are nonsense, and irreconcilable with each other into the bargain, AND are not for Jesus but out loud and expressly for Joseph, who just as loudly was NOT Jesus' father in those stories.)
