How can you calculate what percentage of your race is?

Im Korean, Ecuadorian, and also a bit Indian. My friend said she did the math and found out her percentage of her whole race is. And i think that's sorta weird and that she got it wrong because i doubt she can fin out her percentage of her race and be correct also.How can you calculate what percentage of your race is?
It is very confusing to try to calculate the percentage of each race you are. To get an exact number is completely IMPOSSIBLE. It is impossible to get an exact number because you would have to know the race of EVERY ancestor you ever had, and that is just not possible. The easiest way to get a rough number is to go as far back as your grandparents. For example, if your grand parents on one side are both 100% Korean, and on the other side they are both 100% Ecuadorian, that would make you 50% Korean and 50% Ecuadorian. If One grandparent on one side is 100% Korean, the other is 100% Indian, and both the Grandparents on the other side are 100% Ecuadorian, that makes you 50% Ecuadorian, 25% Korean, and 25% Indian. It depends on what your grandparents are and what percentage of what they are, and you just calculate it. If one of your parents, say your Dad, his parents, one is 100% Ecuadorian, the other is 100% Korean, It makes your dad 50% of both. And your mom is 25% indian and 75% ecuadorian, it would make you 25% Korean, 12.5% Indian, and 62.5% Ecuadorian.

So basically you just calculate it depending on your known ancestors races. If you don't know your ancestors race percentages, you really can't completely find out your percentages of race.

Your friend can calculate what percentage of each race she is, but it is only going to be partially accurate. I know that i am 50% German and 50% Czech, but that is based on my grandparents and does not go any further back than that. I suggest you just start with your grandparents/parents and don't dig any deeper than that.

Good luck!How can you calculate what percentage of your race is?
There is a company called 23 and me that does dna testing. I know caluclating exact percentages is nearly impossible, but the company I speak of offers a map with migratory patterns of where (most of) your ancestors are from. And you can do a rought estimate from that. Plus they offer some other resources in the same package (its not free)How can you calculate what percentage of your race is?
I think it would be possible to calculate the percentage of your race. For example, if your mother's mother was Italian; your father's mother was Spanish; your mother's father was French; your father's father was Mexican, you would be 25% Spanish.
i am 100% of the human race.
