How many animals are color blindness?

Answer 1

there are 1000005000 kinds of blindnesses

Answer 2

* 1 in 12 people have some sort of color deficiency. About 8% of men and 0.4% of women in the US.

* 0.38% of women are deuteranomalous (around 95% of all color deficient women).

* 0.005% of the population are totally colour blind.

* 0.003% of the population have tritanopia.

* Protanomaly occurs in about 1% of males.

* Deuteranomaly occurs in about 5% of males. It's the most common color deficiency.

* Protanopia occurs in about 1% of males.

* Deuteranopia occurs in about 1% of males.

Answer 3

That depends on exactly how you define the term.

Humans are trichromats: our eyes contain color receptors that are sensitive to three different spectral bands.

In "color blind" people, there's something wrong with one or more of these types of color receptors.

Most mammals are thought to have only two types of color receptors. This doesn't make them completely insensitive to color, but it does give them a type of color blindness.

Sea mammals appear to only have one type of color receptor, meaning they can only distinguish between colors based on their brightness.

Answer 4

Approximately zero. Color blindness is not in and of itself fatal. There may be some fatalities from color blind people not noticing warning signs (mistaking a red traffic light for a green one, for example), but it's pretty hard to get concrete numbers on things like that, since if they die as a result it's effectively impossible to prove "they saw the red light and thought it was green" as opposed to "they didn't notice the light at all" or "they knew the light was red, but thought they'd be okay if they ran it away."

Answer 5

color blindness is an x linkedrecessive gene, meaning it is only carried on the x chromosome, not the y, and it is recessive

XC = Allele for normal color visionXc= Allele for color blindness

since it is a recessive trait, the person must have 2 alleles for color blindness if female ( Xc Xc ) or just one if male ( Xc Y )

Because of this, colorblindness is found more often in males than it is in females
