Amino acids: Natural substances that are the building blocks of protein. Astigmatism: An eye condition in which the lens doesn't focus light evenly on the retina, leading to problems with visual sharpness. Carrier: A person with one normal gene and one faulty gene, who can pass on a condition to others without actually having symptoms. Chromosome: In prokaryotes, the intact DNA molecule containing the genome. In eukaryotes, a DNA molecule complexed with RNA and protein into a threadlike structure containing a linear array of genes. DNA:The abbreviation for "deoxyribonucleic acid," the primary carrier of genetic information found in the chromosomes of almost all organisms. Deletion: Loss of a segment of DNA from a chromosome. Enzyme: A protein that helps the body to convert one chemical substance to another. Gene: The basic unit of genetic material Hairbulb: The root of a strand of hair from which the color develops. Hermansky-Pudlak Syndrome (HPS): A rare type of albinism characterized by a problem with blood clotting and a buildup of waxy material in lungs and intestines. Inbreeding: Mating between two closely related organisms. Melanin: Pigment made in the hair, skin and eyes. Nystagmus: An involuntary back-and-forth movement of thDOPA: The common name for a natural chemical (3, 4-dihydroxyphenylalanine) made by the body during the process of making melanin. Photophobia: Sensitivity of the eyes to bright lights and glare Platelets: one of three types of blood cells. The platelet is the smallest cellular element of the blood and is needed for proper clotting. Strabismus: Crossed or "lazy" eyes, often found in albinism. Sex chromosome: A chromosome involved in sex determination. An example is the X and Y chromosomes of humans. Tyrosine: A protein building block found in a wide variety of foods that is used by the body to make melanin. Tyrosinase: An enzyme in a pigment cell, which helps change tyrosine to DOPA during the process of making melanin. Trait: A detectable phenotypic expression of an inherited characteristic. |

Posted on: 02/28/2012 Yeah, in Biology, I learned things such as Punnet Squares. If 2 capital A’s are in the genotype [AA], then they are not albino. If 2 lowercase a’s are in their genotype (aa), then they will be. If it is one of each (Aa), then they will not be albino, but they can pass it on to their kids. You have aa. Someone without albinism in their family at all is AA. If you marry that dude, your child will be Aa (they will not show albinism, but they can pass it on to their kids. If they marry someone with AA, the child will have a 50% chance of AA and a 50% chance of Aa ). If you marry someone with albinism in their family (Aa [actually, they could be AA also, but it is unlikely {it all depends on the parents}]) then your child will have a 50% chance aa (full albino) and a 50% chance Aa (pass it on to their children). Hope that helps. For more info, Google Punnet Squares.

Posted on: 04/23/2012 male cant pass any symptoms because, they are XY and only the X holds the phenotype.
female are XX so they can pass the phenotype.
also male that has it cant hide it, because there is only 1 X. the X holds the genes so female may get XA Xa and that hide the phenotype because there is another X with lower case a. |

Posted on: 02/28/2012 Yeah, just see 2 comments up [pink_y]. Or, just read what I commented here:

Posted on: 09/05/2011 I have a new friend at school that has this. He is the sweetest boy ever and I swear he acts no different than any other teenage boy on this earth [: But I'm always afraid to talk to him about this stuff like asking him questions I basically pretend like I don't notice that he's a black kid that's white. So this was helpful

Posted on: 02/28/2012 No. You have a 1 in 4 chance, though, that you child will have Aa, in which they can pass it on to their children. Otherwise, they will be AA, where they have not albinism at all. I think I just commented on you before. |

Posted on: 08/09/2011 I and my cousine carry albinism gene and neither of us have albinism,is it possible to change one of our gene or is there a way that we can born a healthy baby?
Posted by:

Posted on: 02/28/2012 Not exactly sure I understand. You seem to carry Aa, so if you have a baby dude person with someone who is not related to albinos, your children will not have it. However, your baby dude people will have a 1 in 4 chance each that they will have the same traits that you do. |
