In all possibilities?

Question

ok threw my understanding of genetics isnt there a way that although vary unlikely couldnt there be another person in another city, state, town and maybe even a diffrent country who is my complete opposite becuase there parents had the same allels as my parents (not in the same parent like my dad having Ff and my mom being FF but his dad is FF and his mom Ff) is it possible for me to have this doppelganger even though its not very probable?

not complete opposite, I mean my complete double that looks exactly like me

Answer 1

Sure, it is possible. You wouldn't be their opposite, though. In fact, you'd probably be more like them, since you would still have the same probability of inheriting certain alleles from your parents (FF dad and Ff mom is the same as Ff dad, and FF mom, probability wise, as long as you're not talking about sex-linked traits). Plus, in biology, it is hard to identify opposites, since a recessive trait isn't necessarily the opposite of a dominant one in the context of an organism.

Even if you were exactly alike, or exactly opposite, there wouldn't be that much of an effect since there are so many factors outside of genetics that contribute to your development. Both before and after you were born, external stimuli shaped who you would become. If you cloned someone, for example, they could turn out to be completely different from their 'parent' due to dietary differences, social differences, etc (though they would have the same genetic traits and genetic diseases).

Answer 2

Its possible but the odds are basically infinite minus 1

Answer 3

Yes it is possible but it is so unlikely because you have to measure the percentage of every single gene.

Answer 4

No, it is not possible. Everybody is unique. Your brothers do not like you, even though they have the same parents as you.
