American scientists were able to see the world through the eyes of a cat. Scientists have conducted a brain cat electrodes, which were connected with 177 neurons. Read and decode the signals from the electrodes, the computer shows the display picture that sees the cat. The picture was blurred, but it can be quite clearly distinguish different objects and faces.

The cat 50 thousand genes, which are distributed over 19 pairs of chromosomes.

* Cats gene responsible for red hair color is attached to the floor of the animal, and belongs to one of the X chromosomes. This gene can produce red or black. Thus, a cat with two X chromosomes and can wear red and black colors in her hair. Côte same with only one X chromosome, can be either black or red, but not both simultaneously.

* If the cat still has both red and black color (this occurs very rarely), it will be sterile. The fact that this must have both a cat or female portion of both X-chromosome. This unusual combination of chromosomes and causes that the animal is sterile.
