15 Genes control eye color. Its not the simple 2 genes (Dominant and Recessive) that most people learn in high school Biology. These 15 genes play different roles and have varying levels of influence on eye color. Eye color is almost impossible to predict and it doesn't entirely matter what color the parents' eyes are. Parents that have brown eyes could easily have a child with blue. and vice versa. The level of pigmentation (called melanin) is what determines the color. The less melanin, the lighter the color. Blue eyes have the least melanin in them, brown has the most. every other color is in-between.

Who does color blindness mostly effect?
Everyone can be affected by monochromatic color blindness. Monochromatic color blindness is a condition where your color blind in only one eye.
How many kinds of color blindness is there?
2
How many different color blindness are there?
there are 1000005000 kinds of blindnesses
How many males suffer from color blindness?
1 out of 10
How many alleles for a sex-linked (X-linked) gene does a male carry?
Only one. The X chromosome is bigger and contains things not on the Y chromosome. So if the only copy men have are the diseased copy, then they will have the color blindness or whatever other disease in question. Since the genes are usually recessive, then females would typically have one good copy that is generally dominant. There is a theory that in one type of color blindness, the genes are co-dominant. So instead of just the normal 3 types of cone cells in the eye, or the mutated red cones with the rest being normal, the women with both the normal and the mutated genes end up having both the normal and mutated cones, thus having a greater level of color discrimination than normal.
how many males are effected by color blindness?
more than 199,546 males our color blind
Are color blindness and blindness the same thing?
No - colour-blindness is the inability of the brain to interpret correctly colours that the eyes see, or maybe the eyes have a defect in their structure that sends the wrong signals to the brain. Blindness (total?) is when the eyes are unable to send visual signals to the brain at all. Maybe the optic nerve is damaged, or the eyes themselves are damaged - there are various medical reasons for the cause of blindness.

Is colorblindness a dominant or recessive trait?
Color blindness is an inherited trait that can be passed on through reproduction but it has some peculiarities. It is recessive and not very prevalent in the gene pool. Because of this, color blindness does not appear very often in the population. In addition, it is a sex-linked gene on the X chromosome. Thus males only have one gene to express color vision. If it happens to be the recessive allele, then males are color blind. Females, on the other hand, must have both alleles recessive in order to be color blind.source: ciese.org/curriculum/genproj/activity35.html
