Dizygotic (fraternal) twins may have the same blood type, or they may have different types. Therefore, it may be concluded that twins with differing blood types are dizygotic, or fraternal. However, twins with the same blood type can be either fraternal or identical.
Is spotting more common with twins?
Increased spotting Miscarriages are more common with multiple pregnancies, so a little bit of spotting can be cause for concern. But spotting is also more common with a multiple pregnancy.
What are the signs of twins implantation?

Do you bleed more during implantation with twins?
If you’re pregnant with twins (or another multiple of babies), you might have a greater chance of first trimester bleeding due to causes like implantation bleeding. Miscarriages in the first trimester are also more common when you’re pregnant with more than one baby.
Can twins have different hair colors?
To start with, fraternal twins can look pretty similar, yes. Fraternal twins follow siblings generally: they can be different genders, have different hair color, eye color, sizes, and facial features. But you’ll almost certainly be able to tell they are siblings.
How can you tell identical twins?
When twins are born, the physician is usually able to identify whether twins are identical or fraternal by examining the placenta; identical twins generally share a placenta, while fraternal twins are usually in two separate placentas.
How much do you bleed when pregnant with twins?
The maximum increase depends largely on the size of the conceptus. It is somewhat increased, perhaps to a mean of 1300 ml, in association with the bigger baby of multiparae and increases still more with twins, triplets and quadruplets.
Why would twins end up with different hair colors?
Fraternal twins can definitely have different hair colors naturally. Identical twins can have different hair colors, but not naturally because they come from the same fertilized egg that split, and therefore have the same dna.
Can you see twins at 6 weeks?

What is the scientific reasoning behind mixed fraternal twins?
The scientific reasoning behind mixed fraternal twins is that a person’s skin color is dictated by their genes. With mixed twins, they are born from parents of different skin colors, they inherit different gene codes that influence their skin pigments and bam, there you go.
