Quiz Answer Key and Fun Facts

1. Is it possible to have identical boy/girl twins?

Answer: Yes

It is extremely rare, but there have been at least 3 cases of boy/girl identical twins occuring because of one of an identical male set losing the Y chromosome, creating a girl by default. While these twins are not genotypically identical, they do begin as identical twins.

2. What percentage of identical twins are mirror image (opposite feature) twins?

Answer: 25%

Mirror imaging is characterized by opposite features, such as one twin being right handed, the other left handed, opposite hair whorl patterns etc.

3. What is the overall identical twinning rate in the world?

Answer: 3.5 sets of identical twins per 1000 births

You have a 1 in 285 chance of having identical twins. This figure seems to be universal and random.

4. What was the name of the first set of identical quintuplets to survive?

Answer: Dionne

Annette, Yvonne, Cecile, Marie and Emilie were born in Ontario, Canada, in 1934.

5. Where were the first surviving set of sextuplets born?

Answer: South Africa

The Rosenkowitz sextuplets were born January 11 1974, and are named David, Emma, Nicolette, Grant, Elizabeth and Jason.

6. In 1971 a woman conceived the highest number of multiples. How many fetuses was she carrying?

Answer: Fifteen

The Italian woman had taken fertility drugs which caused her to conceive 10 girls and 5 boys. They were removed on July 22 1971, as it would have killed her to carry on with the pregnancy.

7. There has been more than one case of one woman having 4 sets of quadruplets in her lifetime.

Answer: Yes

Mrs. Zoellner had quads in 1923, 1925, 1927 and 1929. The Kirilow's of Russia also had 4 sets, as did Mrs. Feodor Vassiliev of Russia, and an unidentified man and his first wife starting in 1927.

Fraternal twins can be of different races if conceived at different times by different men. There have been a few cases of this occuring.

14. The only way to know for sure if a set of same sex twins is identical is by DNA testing.

Answer: True

Other ways of guessing zygosity are through placental examination and ultrasound, but the only sure way to know is by DNA testing.

15. You are least likely to have twins if you are of this ethnicity.

Answer: Chinese

The overall twinning rate in China is only 1 in 250, while in Japan it is 1 in 150, 1 in 49 in Norway and 1 in 22 in some parts of Africa.

16. About 1 in 3000 women will have two sets of twins.

Answer: True

The chances of having three sets is about 1 in 500,000.

17. What is the most common natural combination of triplets?

Answer: Two identical and one fraternal

In spontaneously occurring triplets (with no fertility treatments), 60% will be 2 identical and 1 fraternal, while 30% will be all fraternal and 10% will be all identical. Fertility drugs and other treatments have greatly increased the number of fraternal sets.

18. You are more likely to have boy/girl twins between ages 30-39 than any other age.

Answer: True

This is due to the fact that older women may produce more than one egg per cycle, making fraternal twinning more common. You are more likely to have same sex twins (girl/girl or boy/boy) between the ages of 20-29.

19. You are more likely to have sextuplets than conjoined twins.

Answer: False

There have been over 500 cases of conjoined twins documented, and just over 100 cases of sextuplets.

Answer: 60%

About 60% of conjoined twins will die before birth, usually because of sharing multiple organs.
