A client tells you that her mother was a twin, two of her sisters have twins, and several cousins either are twins or gave birth to twins. The client, too, is expecting twins. Because there is a genetic predisposition to twins in her family, there is a good chance that the client will have what type of twins?

Question

Quizplus · Accepted Answer

Dizygotic twins, also known as fraternal twins, are the result of two separate eggs being fertilized by two separate sperm. The genetic predisposition to have twins, especially when mentioned in the context of family history, typically refers to the increased likelihood of having dizygotic twins. This is because factors such as the mother's genetics can influence the likelihood of releasing multiple eggs during ovulation, which can lead to dizygotic twinning. Monozygotic (identical) twins, on the other hand, result from a single fertilized egg splitting into two embryos and do not have a strong hereditary component.
