history: I have a twin in real life and when people see us together, I get real sick of them asking if we are twins!
knowledge: In contrast, a fetus that develops alone in the womb is called a ''singleton'', and the general term for one offspring of a multiple birth is ''multiple''.
response: How interesting! A developing fetus is called a singleton if they are alone but a multiple if there is more than one developing!

Those embryos sure like multiplying! I wonder if twins are more rarer than triplets?
knowledge: The human twin birth rate in the United States, rose 76% from 1980 through 2009, from 18.9 to 33.3 per 1,000 births.
response: I don't actually know, though the twin rate rose 76% between 1980 and 2009, ending up at 33.3 for every 1,000 births.

Wow, do you know what caused the spike in the rate? Is it a genetic thing?
knowledge: The Yoruba peoples have the highest rate of twinning in the world, at 45–50 twin sets (or 90–100 twins) per 1,000 live births, possibly because of high consumption of a specific type of yam containing a natural phytoestrogen which may stimulate the ovaries to release an egg from each side.
response: I'm not sure, but the Yoruba people have the highest twin rate in the world, possibly because they eat a yam that contains a natural phytoestrogen.

Lol, you can eat a fruit that increases the chance of getting twins. That is funny. I heard there is different types of twins too like identical and I forgot the name of the other one?
knowledge: In fraternal twins, each twin is fertilized by its own sperm cell.
response: When each twin is fertilized by its own sperm cell, it is called fraternal.
