How early can twins be detected?
“You can guess as much as you want, but until you have the ultrasound examination, it’s all just speculation,” says Dr. Grunebaum. Luckily, most mamas don’t have to wait long to know for sure. “Today, twins can usually be diagnosed as early as six to seven weeks of the pregnancy,” he adds.
Can twins have different fathers?
It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men. … Identical twins occur if that fertilized egg divides into two separate eggs, early in the pregnancy.

What causes an egg to split into twins?
How Are Monozygotic Twins Formed? This type of twin formation begins when one sperm fertilizes one egg (oocyte). 1 As the fertilized egg (called a zygote) travels to the uterus, the cells divide and grow into a blastocyst. In the case of monozygotic twins, the blastocyst then splits and develops into two embryos.
Which parent carries the gene for twins?
This is why fraternal twins run in families. However, only women ovulate. So, the mother’s genes control this and the fathers don’t. This is why having a background of twins in the family matters only if it is on the mother’s side.
Can I have twins without family history?
Remember, monozygotic (identical) twins don’t run in families—they are random. You may not know if your great-granduncles were identical or not and often there is no way to know for sure without DNA testing. That being said, twins that share a close physical resemblance are more likely to be identical than fraternal.
How do you know if you have twins?
It is impossible to definitively know whether you are carrying twins (or multiple babies) by simply gauging how you feel or going off of what a home pregnancy test shows. In fact, only an ultrasound can confirm a twin or multiple pregnancy.
How do you have boy and girl twins?
Boy/girl twins are always fraternal or (dizygotic); they can only form from two separate eggs that are fertilized by two separate sperm.
How many generations do twins skip?
People with twins in their extended families may wonder whether a crib for two is in their future, too. According to conventional wisdom, twins not only run in families, but they also — for some strange reason — always skip at least one generation.
How can I become pregnant with twins?
Conception happens when a sperm fertilizes an egg to form an embryo. However, if there are two eggs present in the womb at the time of fertilization or the fertilized egg splits into two separate embryos, a woman can become pregnant with twins.
Can anyone have twins?
