Genetics!
Today I learned Basic Genetics. LOL. Here we go:
When learning basic genetics, you get a very narrow picture of how things are inherited. Like for instance, if we are talking eyes and hair, there are more than two alleles (dominant and recessive) that control these features. Furthermore, many times, these genes work together or have co-dominance. In advanced genetics, I learned that though geneticists haven't completely figured it out, there are at least five or six genes that control eye color. A person that has really light blue eyes would have something like aabbccddee and a person with black or dark brown eyes would have something like AABBCCDDEE. A person with hazel/green eyes has AaBbCcDdEe and could be the child od one person with light blue eyes and another with dark brown eyes. There are of course other more complex variations of this, but this is basic.
So let's pretend...
Your mother has medium blue eyes : AABBccddee
Your father has dark brown eyes: AABbCCDDEE.
Your genes could be:
1. AABBCCDDEE (dark brown)
2. AABbCCDDEE (dark brown)
3. AABBCCDDEe (dark brown)
4. AABbCCDDEe (dark to medium brown)
5. AABBCCDdEE (dark brown)
6. AABBCCDdEe (dark to medium drown)
7. AABbCCDdEE (dark to medium brown)
8. AABbCCDdEe (medium to light brown)
9. AABBCcDDEE (dark brown)
10. AABBCcDdEE (dark to medium brown)
11. AABBCcDdEe (medium to light brown)
12. AABBCcDDEe (dark to medium brown)
13. AABbCcDDEE (dark to medium brown)
14. AABbCcDdEE (medium to light brown)
15. AABbCcDDEe (medium to light brown)
16. AABbCcDdEe (light brown - hazel)
The child can get any of those combos and the lightest the child's eyes will be is hazel. There are other more complex factors which is why eye color cannot be exactly determined by the genes (hence the spectrum given behind the genes) and geneticists are unsure how true green or yellow is formed. If given to probability, this child will most likely have dark brown to medium brown eyes. There are about 20 different combinations (5 genes times 4 [2 alleles from the mother, 2 alleles from the father]) of the mother's and father's eye genes that this child can get, but since the mother and the father are the same in the A gene (both AA), I didn't make more combinations than needed.
So... I'm AaBbCcDdEe. =D So what are you, my dear reader? =) I remember some of what I learned in bio... which was like, 3 or 4 years ago? LOL. About how yes, Height wise the tall height genes are more dominant than that of short height genes. How Dark brown is dominant while blue and green are recessive. How dark hair is dominant and pale hair is recessive, etc. I think genetics are so fucking interesting. Maybe I shall think about putting my future along that pathway =D It's so exciting
Everything I stated which is italicized, I learned from a fellow Eurasian. There was a question on the forum about genes and the probability of things. Most Hapas on that site have dark brown to medium brown eyes and dark hair though. It's interesting how that pretty much makes it obvious how those traits are so dominant.
I sometimes feel like a loser being in there while only being 1/5 asian. But 1/5 is much more than 1/18. Some chick is on there while being 1/18 english. if you ask me, once you get into double digits - then it doesnt really count anymore. It is probably already out of the gene pool.

I guess I'm AABBCCDDEE. I'm boring and dark brown. (Reply to this) (Thread) |

Actually, you aren't necessarily AABBCCDDEE. You could be any of the other dark brown varieties. Dan, you are so stoopid, how are we supposed to know our own genetic code??
