African-Americans are not known to have blue eyes, but they are rare. Here are some ways an African American can get blue eyes: If it's not a rare genetic condition, what about other possibilities? It is possible that there are white relatives on your mother's and father's side of your family.
A ko mọ awọn ọmọ Amẹrika-Amẹrika lati ni oju buluu, ṣugbọn wọn ṣọwọn. Eyi ni diẹ ninu awọn ọna ti Amẹrika Amẹrika kan le gba awọn oju buluu: Ti kii ṣe ipo jiini ti o ṣọwọn, kini nipa awọn iṣeeṣe miiran? O ṣee ṣe pe awọn ibatan funfun wa ni ẹgbẹ iya ati baba ti idile rẹ.
The reason it takes a few generations to see something like blue eyes is because it is genetic.. Our example simplifies eye color (the genetic makeup of eye color is complex) but does the same thing. Remember that for most genes, you have two copies of each gene, one from your mother and one from your father.

The brown form of the eye gene (B) is dominant in the recessive blue form (b). Dominance means that if one of your genes is type B then you will have brown eyes - blue with a hint of brown.How can two brown-eyed people have a blue-eyed child? The best way is if both are carriers of blue eyes (Bb). Either parent can pass on the b version of the gene so that the child has bb and has blue eyes.

Dominance tumọ si pe ti ọkan ninu awọn Jiini rẹ ba jẹ iru B lẹhinna iwọ yoo ni awọn oju brown - buluu pẹlu itọka ti brown.Bawo ni awọn eniyan oju-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-awọ-buluu?

If only one gene is involved, the chance of a child having blue eyes would be 1 in 4. One of the ways that blue eyes can stay "hidden" for a long time is if there is constant intermarriage between Bbs (brown-eyed people whose eyes are blue) and BB. You can only get brown eyes from this combination - BB parents can only contribute B cells. The genes involved are also more complex, making it more difficult to have blue eyes. There are at least two genes, and possibly more, that contribute to eye color.

All of your paper must be of a blue color to have a blue eye. This makes blue eyes rare. What if there are no ancestors in your family? Another possibility is that the primary eye cells in you have been changed or altered so that you now have blue eyes. These types of mutations are rare, but that's where the wonderful diversity of people you see around you comes from. You can be a pioneer in genetics!
