My parents have brown eyes and mine are blue; Why? And I am not adopted.?

Answer 1

There are two possibilities here:

1) both of your parents have a recessive gene for blue eyes. If that's true then there is a 1/4 chance that they could have a child with blue eyes. Look at your grandparents. Do you look like any of them??

2) look at childhood pictures of your parents. Hair and Eye color can change over time (especially through puberty). I had blond hair and blue eyes as a child. I am now 24 and I have light brown hair and hazel eyes.

Answer 2

That's a good one. I come from a family of 9, including parents and I have one sister with blue eyes. The rest of us have brown. I think you would have to understand genetics to get a truly good answer. I will follow your listing to see some of the answers.

Answer 3

Well, you are apparently healthier than they are as you are much younger. Just to check this theory out, get any of their photos out (color) from when they were younger or even babies. Ask them if their folks remember what color their eyes were when they were born if they don't recall. They might have been blue at one time. Books on iridology will explain the change in colors if they were born with blue eyes.
"Irides are basically blue, basically brown, or mixed. A miasmic iris is also called a "dishwater eye" because of its murky, lackluster color. The effect is often from some type of body pollution, such as a medication or environmental toxin." http://library.thinkquest.org/24206/iridology.html
Many conditions can change eye coloring;

If that doesn't explain it, I'm not sure what it can be attributed to.
Maybe you don't belong to the man your mother thinks or says you do?

each guy or woman has 2 genes that be certain eye coloration. Brown is a dominant gene, so your mom and dad eyes seem brown even nonetheless they have one brown and one blue gene. each of your mom and dad would desire to have given you his and her blue gene once you have been conceived. Couples like your mom and dad have a a million in 4 risk of having a infant with blue eyes. additionally, one in all your brown eyed grandparents lots have had a blue recessive gene and that's how his or her infant have been given it. it could be much less complicated to describe if i'd desire to draw a chart.
