A woman is 28 weeks pregnant with twins. The ultrasound reveals that one twin is a boy and the other is a girl. The woman asks if her babies will be identical. The nurse will base her answer upon which of the following information.
Genetic testing when the babies are delivered will need to be done to determine this.
They are dizygotic because the ultrasound shows one is bigger than the other.
The twins are dizygotic because they are not the same sex
They are monozygotic because they are in different amniotic sacs.
The Correct Answer is C
A. Genetic testing is not necessary to determine if the twins are identical. Identical twins come from the same egg, while fraternal twins come from separate eggs.
B. The size difference alone does not determine whether twins are identical or fraternal.
C. Dizygotic twins (fraternal twins) are always of different sexes. This is because they are fertilized by two separate sperm and develop from two separate eggs.
D. Monozygotic twins (identical twins) occur when one fertilized egg splits into two embryos. The fact that they are different sexes rules out the possibility of monozygotic twins.
