Question

i wanna know why some mammals have so many colours on their body?

Answer 1

Tortoiseshell cat otherwise a calico cat

Tortoiseshell and calico describe a coloring found in cats caused by a combination of specific genetic traits. It is a mix of phaeomelanin based colors (red) and eumelanin based color (black, chocolate and cinnamon). Cats of this coloration are believed to bring good luck in the folklore of many cultures.

Answer 2

Many black or red cats are white on their belly and some other parts of their body. It is very common in animals to be darker at the upper side than at the lower side. The upper side is more likely to be visible and often has a camouflage- or signaling color or pattern, or is dark to protect against sunlight. The lower side will often be white as it is the cheapest color for the body to produce (requires no pigment). The white trait works as a cancellation of any pigment production and will dominate any color gene in the regions where it is expressed.

The red gene is dominant relative to other colors, so whenever the red gene is active, the cat becomes red everywhere where pigments are produced at all. So a male cat can be red and white, but not red and black.

Female cats can be red and black or red and gray, though. This is because the red gene is located on the X chromosome. Females have two X chromosomes, but in order to get the same X chromosome activity as in males, either of the two X chromosomes is silent. If the silent X chromosome contains the red gene, some other color is allowed to be expressed.

Now the trick is that which of the two X chromosomes is silent varies from cell to cell. Since it's like flipping a coin, red/black female cats typically are 50% of each. You'll rarely find a cat that is, say, 90% black and 10% red.

Answer 3

Cats and other domestic animals are mostly colored by selection of humans. Wild animals are mutli-colored for good camouflage when hunting or hiding. A mottled coat is easier to hide in shadows and high grasses than a solid color. The multicolored pattern breaks up the visual field better and is harder to distinguish from the background.

Answer 4

Each descendant has the genes from both parents. Random breeding generates random coloration. When black and white and yellow and striped animals are breeding, you can easily get multi colored spotted breeds.

;-D Life is a colorful occupation.

Answer 5

genes have got somethinh to do with it
