Humans have three types of cones in their eyes, which are responsible for color vision.

There are three types of cone receptors in the human eye: short-wavelength cones (S-cones), medium-wavelength cones (M-cones), and long-wavelength cones (L-cones). These cone receptors are responsible for color vision and the perception of different wavelengths of light.
Brown eyes are a dominant trait in many humans, meaning that if one parent has brown eyes, their child is likely to inherit this trait.
There are three types of cones; ones that measure the intensity of red light, one that measures the intensity of green light, and the third measures overall intensity of light. The brain then takes this information and deduces the amount of blue light present.

Nocturnal animals in general have many rods than cones in their eyes. Rods are used more for dim light and seeing motion.
Humans have three types of color-sensitive cells, known as cones, in their retinas. These cones are sensitive to different wavelengths of light, corresponding to blue, green, and red. This trichromatic vision enables humans to perceive a wide range of colors by combining the signals from these three types of cones.

Research has found that dogs have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of colour vision that we do. It is thought that dogs can see blues and yellows the best and that they are able to differentiate between various shades of blue and violet, but that they have difficulty distinguishing reds from green. They are considered similar to red-green colour-blind humans.
Humans have two eyes but when people have disorders it may vary.
If by we you mean us humans, then two.
No it is not true. It is a common misconception that dogs see only in black and white. Research has found that dogs have colour-sensitive cones in their eyes, but not as many as a human's.

Yes, homosexuality is present in more than 1,500 species, including all species of mammals and birds, as well as many others, but homophobia is only present in humans.
There are 28 people present and 35 dogs present
about 24 cones
It is thought that all dogs can see in limited colour. It is a common misconception that dogs see only in black and white.
