When eggs are fertilisedout the mother's womb furing body fertility treatment and then implanted in her womb..

Question

will they produce similar or identical offspring and why?

Answer 1

The separate eggs will not produce identical offspring as each other because they were separate eggs all along. Identical twins are created when a single fertilized egg splits, therefore ALL the genetic material is exactly the same. There is a possibility, though, that one of those eggs could split and produce identical twins - but again, it wouldn't be possible for multiple eggs implanted at the same time to produce identical twins.

Answer 2

Identical offspring have to come from the same egg that splits during development. These offspring share identical DNA. Separate eggs fertilized and then implanted will produce individual offspring each with their own DNA. If the eggs and sperm came from the same donors, the offspring will be similar because they share the same biological parents. If the eggs and sperm came from different donors, the offspring will have widely different physical and personality characteristics, as different as their biological parents.

Answer 3

Each egg/sperm combo is unique. The same parents frequently produce similar offspring, but not always.
If an egg/sperm combo [ fertilized egg, or ova ] replicates itself and divides, you get identical twins, same as the old fashioned way.

Answer 4

I think it would depend on the doner. If the father is the same then it would produce children that look like family. The same way as if they were fertilized in utero.

Answer 5

do you mean will fertility treatments cause identical twins?

Answer 6

what?
