What type of cat would be the best control to compare with Calix?

Only the mother has two X chromosomes. The father is male, so he only had one X chromosome but the calico cat has a genotype of XXY. Only nondisjunction could cause Calix to have an XXY karyotype.

Explanation:

Cats with these combinations appear: white with orange spots, white with black and orange spots (calico), and white with black spots, respectively. The actual genetic composition is called the genotype, and the expression of the genes is the phenotype. Thus, calico is the phenotype for a cat with the genotype.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
