Which is the correct term for Identical Twins?
Correct Answer
B. Monozygotic
Explanation
The correct term for identical twins is monozygotic. This term refers to twins who develop from a single fertilized egg that splits into two separate embryos. Monozygotic twins share the same genetic material and are typically of the same sex. This is in contrast to dizygotic twins, who develop from two separate eggs fertilized by two different sperm, and may have different genetic makeup. The terms monochorionic and monoamniotic refer to the number of placentas and amniotic sacs in the pregnancy, respectively, and are not specific to identical twins. Polyzygotic is not a recognized term in relation to twins.
2.
Which of the following is false?
Correct Answer
C. Identical twins always share the same placenta
Explanation
Identical twins do not always share the same placenta. In some cases, identical twins can have separate placentas, which is known as dichorionic diamniotic twins. This occurs when the fertilized egg splits within the first few days after conception. So, it is false to say that identical twins always share the same placenta.
3.
Which of the following is said to increase your chance of having twins?
Correct Answer
D. Yams
Explanation
Yams are said to increase the chance of having twins because they contain a higher level of a chemical compound called phytoestrogen, which is believed to stimulate the release of multiple eggs during ovulation. This can potentially increase the chances of conceiving fraternal twins. However, it is important to note that the effect of yams on twin conception is not scientifically proven and more research is needed in this area.
4.
Identical twins are always the same gender.
Correct Answer
A. True
Explanation
Identical twins are formed when a single fertilized egg splits into two separate embryos. Since both embryos come from the same fertilized egg, they have the same genetic makeup. This means that identical twins will always have the same gender because their genetic sex is determined by the chromosomes present in the fertilized egg. Therefore, it is true that identical twins are always the same gender.

10.
All twins are born via a cesarean section?
Correct Answer
B. False
Explanation
The statement "All twins are born via a cesarean section" is false. While it is true that some twins may be born via a cesarean section, many twins are born vaginally. The method of delivery for twins depends on various factors such as the position of the babies, the health of the mother and babies, and the recommendations of the healthcare provider. Therefore, it is incorrect to say that all twins are born via a cesarean section.
