I have a twin in real life and when people see us together, I get real sick of them asking if we are twins!
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?
Well, the twin birth rate in the US rose from 18.9 to 33.3 for every 1,000 births between 1980 and 2009
Wow, do you know what caused the spike in the rate? Is it a genetic thing?
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?
When each twin is fertilized by its own sperm cell, it is called fraternal
