I find genetics to be a particularly interesting field of biology as it deals with the molecule of heredity – DNA.
I think it is crazy to think about how unique each one of us are because out of all of the possible gametes (sex cells) two people can make, there is a 1 in 70,368,744,177,664 chance that you turned out to be you!
1 out of 70,368,744,177,664!
Isn’t that crazy?! It is nearly impossible for you to be you!
Another intriguing aspect of genetics is figuring out the relationship between two living things. Do you think it’s impossible to be related to every human on Earth? Check out this Vsauce video to find the answer.
