Some animals are color blind... Just some can see some certain colors, like a horse can see blue's and greens, deer can see yellows and greens..etc...
Dogs most definitely are not color blind. There are some differences in their vision from that of humans, but -- contrary to popular myth, their eyes contain both rods (cells that detect light and movement but not color) and cones (which detect color and need more light than rods do in order to activate).
Rods are groups of light sensors connected to one neuron. Cones, on the other hand, are one neuron per cone and, unlike rods, have a narrow range of wavelengths they'll respond to. Dogs' cones respond to the human range of yellow, and blue-indigo.
Most breeds of dogs also do not resolve images well at distance, with a focal range of about 20/70 (to a human's vision of 20/20). This means, what you see at 75' is about what a dog sees at 20' (exceptions are Labrador Retrievers, who approach 20/20 -- which is why they're often used as guide dogs).
Dogs also have a wider angle of acceptance -- around 270 degrees (as opposed to a human's 180 degrees). This means they are more aware of events on the periphery of human sight of course, but as the acceptance angles of vision of the two eyes don't intersect as completely as humans, they don't get really good distance ranging except for a small angle of acceptance directly in front of them.
You can pretty easily test this if your dog likes retrieving. Get a bunch of identical balls in different colors, and watch for the surprisingly different reactions.
Birds are not color blind because you can teach a parrot to recognize colors. This is also true in a peacock's colorful wings.
Good point! While dogs have only two types of cones (see above about cones and rods) that detect yellow and blue-indigo, and humans have 3 (Cyan, Magenta, Green or Red/Yellow/Blue), birds have four, with the ability to see into the ultraviolet as well.
Pure white, Persian long-haired cats, are color blind.
One in four human males has a form of colorblindness, with differing levels of severity, or acuteness.
Deer are color blind. This is why hunters where blaze orange. It stands out for the hunters, but isn't noticeable for the hunted.

What is the probability that a colorblind female and a normal color vision male will produce an colorblind offspring?
100% of all male offspring will be colorblind. 0% of all femal offspring will be colorblind.
What is the probability that a woman who is a carrier of the colorblind gene and a colorblind man will have a daughter who will be colorblind?
the colorblindness is usually not activited in a female body but is usually seen in male
What is the probability that a colorblind women and a man with normal vision will have a colorblind son?
50%Answer100%
If a normal woman whose father is color-blind marries a colorblind man what are their chances of having a colorblind son?
50%
A colorblind man and woman with normal vision whose father was colorblind have a son what is the probability that their son is colorblind?
Make a punnet square with the mother above, her genotype would be: X^B X^b, and the father to the left whose genotype is X^b Y.The probability of having a colorblind CHILD is 50%. The probability of them having a SON is 50%. Since we are asked what the probability of their SON being colorblind, it is 50% as well. The reason is because the chance of having a colorblind son, among sons only, (according to the punnet square) is 50%.
What if Mary and her mother are both colorblind is Mary's father colorblind too?
If Mary's mother is colorblind, and therefore carries the colorblind gene on one of her X chromosomes, then Mary would inherit that gene as well. If Mary's father is colorblind, he would have to pass on his X chromosome with the colorblind gene to Mary, making her colorblind too. If only Mary's mother is colorblind, Mary's father is likely not colorblind.
Is Taylor Lautner colorblind?
No, Taylor Lauter is not colorblind.
Are rhodesian ridgebacks colorblind?
All dogs are colorblind.
Is a carrier for colorblindness is colorblind?
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.
What is the probability that a colorblind female and a normal color vision male will produce an colorblind offspring?
100% of all male offspring will be colorblind. 0% of all femal offspring will be colorblind.
How do dogs get colorblind?
They are born colorblind, they don't just become it.
What is the life expectancy for people that are colorblind?
The same for a person who is not colorblind
When was Colorblind - book - created?
Colorblind - book - was created in 2010.
When was The Island of the Colorblind created?
The Island of the Colorblind was created in 1997.
Are donkeys colorblind?
Nobody really knows, people say cats are colorblind when they are not really. So I would say "No." donkeys are not colorblind
What is the probability that the son is colorblind if the moms colorblind and the father isn't?
100
How many pages does Colorblind - book - have?
