Can dizygotic fraternal twins be conceived a week apart?
I think so. My twins are three days apart according to every ultrasound so far. It seems perfectly reasonable that they could be up to a week apart especially considering that is about how long strong sperms keep on working within the right environment. I am not a Dr., but my guess would be it must be possible. Take care While it is possible for non-identical (dizygotic/2-eggs) twins to be conceived apart (and by different fathers!), it's generally not the case. An ultrasound showing twins differing in age by 3 days is not significant given the margin of error for ultrasound technology. Just like most adults are different sizes, so too are babies in utero owing to genetic and environmental factors.
What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
