There is Excessive Hair loss from my chest. And I always forget where I kept my mobile at home. Is this a sign of alzheimers disease? Dandruff in hair, if I wash my hair, it decreases, but again the next day it increases.
Can you tell me in human beings, brown eyes are usually dominant over blue eyes. Suppose a brown-eyed woman whose father had b?
Eye color: Is genetically complex with a number of factors that determine the actual color appearance. However the brown gene is dominant and the blue gene is recessive. Since only one dominant gene is required for brown eyes, then brown eyed parents can produce blue or brown eyed children, while two blue eyed parents should produce only blue-eyed children. ...Read more
Either: Patients with both blue and brown eyes can be sensitive to light, although, in general, people with lighter eyes tend to be a bit more light sensitive. ...Read more
Eye color: Some people's irides have a mixture of browns and blues that cause their eyes to appear blue when they wear blue clothes and green when they wear green. ...Read more
Nice: It means they think you have good looking eyes. Thank them. ...Read more
Genetics: There are at least five different sets of genes that control eye color. Chances are if you researched your family history someone somewhere down the line had similar eye color. ...Read more
Yes: Blue eyes have less pigment in the iris and therefore transmit light to the retina easier, increasing light exposure and sensitivity. Not all blue-eyed people are abnormally sensitive to light. Adaptation can happen, as well as the wearing of sun glasses for protection and comfort. ...Read more
Yes it can: Latisse (bimatoprost) is in the postaglandin analogue drug class. These drugs were invented to treat glaucoma by lowering eye pressure. Side effects growth of eyelashes, red eyes, and redness of the eyelids. They can also cause reactivation of herpes virus in the eyes, leading to inflammation and loss of vision. Long term use can cause increased pigmentation of the iris, making blue eyes brown. ...Read more
Not really: The genetics of eye color is complex but my understanding is that brown is dominant over blue which is recessive. Each parent contributes one copy of one of a pair of genes. If both parents have brown+blue gene they will have brown eyes but each may pass on the blue gene to the infant resulting in expression of blue eyes. One brown gene dominates and produces brown eyes in most cases. ...Read more
Absolutely: No need to blame the milk man. ...Read more
Easy one: Brown gene dominates over blue so parents only need one of 2 genes to be brown. Blue eyed infants must get one blue gene from both parents, so in this case both parents carry one blue gene. Nothing spooky here, just basic genetics. ...Read more
Yes: There are at least 5 different sets of genes that control eye color. ...Read more
No-many variables: You get 1 eye color gene from both parents. Brown dominates, so they could be brown with 1 brown & 1 blue gene (Bb) or 2 brown genes (BB).A blue eyed parent would only have blue genes (bb).Two Bb brown eyed parents could conceive blue eyed babies every time but statistically only 25% is expected. A BB brown and bb=blue eyed parent would have all brown eyed babies. Two bb blue eyed parents have blue ...Read more
Brown over blur: The inheritance of eye color is somewhat complex but when it comes to brown v. blue --- brown is dominant over blue. In your family, Mom and Dad probably have brown eyes but carry one gene for brown and one for blue. There is a 25% chance of a child in this mix with blur eyes. All other combinations will be brown. It is a matter of statistics. ...Read more
Blue requires 2: Dominent genes (a) require only one coded gene from a parent to express a color, while a recessive gene (a) requires a pair. At conception you get genes from both parents. Daddy brown eyes aa or aa donates one (a or a)& mommy brown eyes aa or aa donates the other. The baby could have aa, aa, or aa. If aa then eyes are blue. If you have blue eyes, your brown eyed parents were both aa (carriers of blue). ...Read more
Yes: This has to do with inheriting the OCA2 eye color gene. It will determine if an eye color is brown if present. ...Read more
Why does a fetus at 32 weeks has blue eyes regardless of what it real color will be? What cause this phenomena?
Melanocyte migration: The melanocytes destined to migrate to the iris are not mature yet for several months after birth - which is why a lot of newborns have light-color eyes but they turn darker as they go past their first birthday. This is normal. ...Read more
I have brown hair brown eyes, husband has blue eyes blonde hair fair skin, will baby most likely have brown eyes and brown hair?
Difficult to say: The genetics of human eye and hair color are very complex--you can pin the odds down better the more genetic history of eye and hair color you can obtain--siblings, parents, aunts and uncles, grandparents, great-aunts and uncles. There are odds tables based on this information. Accurate prediction is possible with DNA analysis: 45 mutations in 12 genes for hair color. ...Read more
Can camera flash change the baby's eye color? For e.g, can blue eyes turn hazel due to the use of flash while the baby's eyes are still developing?
No: A baby's eye color cannot be changed by a camera flash. The eye may darken normally during the first few months of life however. ...Read more
I have light brown eyes, my mom has blue eyes, husband has blue eyes, blue eyes run in his family what are the chances of our baby having blue eyes?
50% per conception: If both your husband and mother have blue eyes and yours are brown, you are a carrier of a blue eye gene. Your brown gene dominates your blue, so yours are brown, but since dad can only donate a blue gene, your offspring will have 1 blue gene from him and either blue or brown from you. Your kids have equal chance of being blue or brown. ...Read more
Yes: The iris is a barrier with an expandable hole in the middle through which light passes to the retina. Its function depends on blocking all light that doesn't enter the hole. All iris pigments leak a little light, called "straylight, " causing glare and mildly decreasing visual acuity. Blue pigment happens to leak the most light. Of more consequence is blue-eyed individual's skin photosensitivity. ...Read more
