Then why did she say “I can’t explain it.”?
“I don’t know who the father is” is really easy explanation if the father is an unknown person. Or “his father wasn’t around and I raised him myself”. Or maybe “I don’t want to get into it” if it was an unwilling pregnancy related to her status as a slave
“I can’t explain it” implies she can’t trace it back to a person (or group of people) at all.
Anakin not having a biological father is a major factor in the council seeing him at all despite his being already “too old” for training according to Yoda. If he weren’t unique the council wouldn’t have wasted their time with him and just rejected a meeting all together.
If it’s a perfect copy, without a doubt we’d try to kill each other as soon as the confusion of the situation wore off. We might not succeed, but we’d try.
