5 Fuzzy Lop Bunny

Isn't he a cute bunny? He looks so cuddly.

We had a neighbor's Siamese cat that got injured in the winter. The veterinarian shaved part of the cats fur off to put in stitches. That cat had patches of dark fur for years.

Why did the fur grow in dark colored, where it had been shaved?

Siamese cats have a faulty gene that flubs up the production of the enzyme Tyrosinase.
This causes the cat to only be able to make pigment where his skin gets cold, and even then the pigment doesn't come in in full strength.

I love Siamese cats, they have so much personality, but then I learned that cats with the heat sensitive color have vision problems.

Why would a heat sensitive color pattern affect vision?

Remember the reason Siamese cats are colorpoints (the body is lighter colored than the ears, face, tail, and legs) is because they have a mutation that flubs up the production of the enzyme Tyrosinase.

Genes work like letters in a book.
What if your computer changed every letter "b" that you typed into the letter "f"?
Your bunny would be funny.

"c"s into "h"s: on Sunday people would go to hhurhh.
"c"s into "m"s: Cute would mean mute.

The basis idea is that when you change one gene, you might only see one change, but there are other changes inside, because each gene codes for different things, like the letters on your keyboard aren't just used for one word.

We don't know what all the changes will be when we change the genes in an animal. When you change the ears, you aren't just changing the ears, you are changing one of the letters in the alphabet in the animal's book of life.
