Is there a word for twins who don't look alike?
Yes, non-identical twins are often referred to as fraternal twins. These twins develop from two separate eggs fertilized by two different sperm cells, resulting in genetic differences that can make them look less alike than identical twins.
If two girls are twins is it possible for one to be white and one to be black if their mom is black and there dad is white?
Yes, it is possible for twins to have different skin tones if their parents have different genetic backgrounds. This can occur due to genetic variations that result in differences in skin pigmentation.
Do twins have to have the same father?
They don't. There are two types of twins, fraternal and identical. Current research shows no genetic connection to having Identical twins, anyone can have them. Fraternal twins are caused by a female trait, dropping more than one egg at a time. There appears to be evidence that the trait can be inherited. While it appears to be on the mother's side of the family, it is certainly possible that this could be transmitted on the male side as well. This double dropping also occurs with older women as well.
Twins who delevelop in separate amniotic sacs?
Twins who develop in separate amniotic sacs are known as dizygotic or fraternal twins. This means they were conceived from two separate eggs fertilized by two different sperm cells. Dizygotic twins can have different genetic makeup and are no more similar than siblings born at different times.
How do you determine who is the father if identical twins have same dna?
Identical twins will have the same father, so a paternity test is done just like for any kid. With fraternal twins, it is possible, but very, very rare, to have different fathers for the babies.
What are the three types of twins?
There is Identical twins, Nonidentical twins and Conjoined twins.
What is another name for nonidentical twins?
dizygotic
How many pairs of twins your there in the world?
10 million identical and 115 nonidentical.
How is it possible for twins to have different fathers?
It is possible for twins to have different fathers if the mother releases multiple eggs during ovulation and has intercourse with two different men within a short timeframe. Each egg can be fertilized by a different man's sperm, resulting in twins with different biological fathers. This phenomenon is known as heteropaternal superfecundation.
What are nonidentical twins?
Non-identical twins occur when the mother ovulates and two separate eggs are released and fertilised. This is different to identical twins, they occur when one original egg splits n two and develops in tandem. then yo have sex
Is it possible for a woman to have twins from two different fathers"?
Yes, it is possible for a woman to have twins from two different fathers. This rare phenomenon is known as heteropaternal superfecundation. It occurs when a woman releases multiple eggs during ovulation and has sexual intercourse with different partners within a short timeframe. Each egg can be fertilized by sperm from a different man, resulting in twins with different biological fathers.
Can fraternal twins have different fathers?
Yes, it is possible for fraternal twins to have different fathers if the mother has had intercourse with more than one man during her fertile period. This phenomenon is known as heteropaternal superfecundation.

Do most pregnancies start out as twins?
No, most pregnancies do not start out as twins. When the ovaries release two eggs and both are fertilized then will twins be born (fraternal/nonidentical twins). Or a fertilized egg may divide before implantation resulting in identical twins.
Is it possible for a mother to have fraternal twins with different fathers?
Yes, it is possible for a mother to have fraternal twins with different fathers, a phenomenon known as heteropaternal superfecundation. This occurs when a woman releases multiple eggs during ovulation and has sexual intercourse with different partners within a short timeframe.
How do you get nonidentical twins?
Non-identical twins happen when two eggs are fertilized at the same time. This happens when the mother ovulates twice, so she has two separate eggs that can be fertilized and develop into fetuses.
