Today I learned why calico cats are colored the way they are. Female cats have two X chromosomes and on each of thoes chromosomes is a gene that codes for either black hair or orange hair. So in calicos they have portions of skin where the X chormosome with the black gene is dominant and portions where the X chromosome with the orange gene is dominant. So where there is balck hair the X chromosome with the black gene is the chromosome that is being read by the RNA. This results in the pretty coloration. And this is why there are very few calico males, because there needs to be 2 different X chromosomes. So calico male cats are actually XXY.

And I also had to add this in from my very charming physics book. Even my TA said that he can tell the book is poorly written and he is far from a native english speaker.

"The story of the boy and his toys goes like this. One there was a little boy who had some toys. Mostly, the toys stayed in the boy's room. Every now and then his mother would clean up his room and put the toys away where "they belonged". But as soon as she finished picking up and left the little boy alone in his room, he began to interact with the toys. Soon they were again scattered all over the room. And no matter how much the mother wished it would be so, it never happened that after the boy and the toys interacted, they ended up back "where they belonged." That is, after the boy and the toys "came to equilibrium," the toys were always scattered all over the room."

What?

I also learned last week that Kelp is NOT a plant. It is a protist, in kingdom Protista, domain Eukarya.
