Anonymous: Thanks for your blog; even as a huge genetics nerd I never realized how unhealthy white tigers and ligers are. Do you have any thoughts on small cat issues that you would like to impart to us?
Small cats as in domestics? I’m not aware of genetic issues with lesser cats other than your standard inbreeding issues(along with color morphs like melanistic and leucistic cats), but I know with domestic cats inbreeding is also a problem, as well as breeding for specific morphs. Aka, “push-nose” cats are predisposed to a lot of issues, mainly breathing issues, and munchkin cats can have a lot of bone and developmental issues. Calico cats are nearly always female, and orange tabbies are almost always male. Oh, and 65 to 85 percent of all-white cats with blue eyes are born deaf. If that doesn’t say enough about the intricacies of domestic feline genetics and faults therein I don’t know what does. But that’s what a really long time of selective breeding does I suppose.
Sorry to be that person, but could you be careful correlating the male orange tabby with the calico/tortoiseshell pattern? Orange cats are just as likely to be female as male. The calico/tortoiseshell comes from the black and orange coat colors. Both colors are X-linked (located on the X chromosome), which is why tortoiseshells or calico cats are almost exclusively female. Males, being XY in most cases, only have the one X chromosome passed from their mother, thus only one of the colors is passed down: orange or black.
For example, if you have an orange mother and a black father, all the sons will be orange and all the daughters will be tortoiseshell/calico. However, if you have a black mother and an orange father, you’ll get only black sons and calico daughters. If the mother is calico/tortoiseshell and the father is black, you’ll find the daughters can be calico or black, where the sons will be black or orange. If the father is orange with a calico mother, calico or orange daughters and orange or black sons.
Hmm? I’m not understanding what I said wrong, by your (really detailed!) explanation it looks like we line up on this. I had learned in my previous job that orange tabbies are predominantly male, I didn’t know this was incorrect?
I keep hearing that orange cats are usually toms but my dad’s old cat Sophie was an orange tabby female and I didn’t really consider her or her mixed breed littermates to be anything unusual. Was Sophie really a rare mutant this entire time?
It is true that orange cats are more likely to be males, but I wouldn’t say “almost always.” It’s more like a 75% chance they will be. I actually work at a vet’s office and happened to ask one of our doctors about this the other day (who is a highly qualified feline specialist) and she confirmed it. Like the previous poster said, there are two main colors in cats, orange and black, and they are carried on the X chromosone - a male cat only has one to express color, hence why they are (almost) never calico/tortoiseshell, aside from mutant individuals. Since females are XX, both of the parents need to be at least carrying orange (calico x orange or orange x orange) to make an orange female, whereas with males they just need one of their parents to have the gene. So orange females are significantly less common than orange males, but not exactly rare either :)
getting along pretty well with my new co-worker
I show affection for my pets by holding them against me and whispering I love you repeatedly as they struggle to escape from my arms
sketch from earlier with some color! not sure what i was aiming for but it was nice to just relax and paint. may go back and finish it eventually, happy for now though
drawin some kitties (full size in new window)
Anonymous: Have you tried using Vimeo? c:
I looked into it a while ago, they had some pretty serious copyright restrictions though and since a lot of my videos use 3rd-party music I didn’t want to risk it. I could always remove/swap sound, but I generally either draw the picture with a song in mind or choose it very specifically so I’d like to keep it together. Pretty much the main reason I’ll probably end up sticking to YouTube.
Anonymous: When are you planning to put your videos (and your new animation) back up? (not rushing you,just curious)
I’m currently looking for a better video-hosting alternative than YouTube (I just really dislike the community there and got tired of dealing with it) so I either need to find a host that works better or (more likely) go through and re-upload my videos on a separate account so I can have better control of them. For what it’s worth, they’re all currently unlisted so if you have any bookmarked or they are hotlinked in my art’s description you can still watch them in the meantime!
