A date with Dr Travis Wyman

So after a bit of diving around the internet I have found a few videos and podcasts starring our very own @t_h_wyman (he is probably going to hate me for this with the amount of questions he is likely to receive)

If you’re like myself and enjoy his rambles and seeing him constantly correcting hosts then this is the thread for you :grin:.

I’m sure there is more out there but these are the ones I have found so far.

Enjoy :blush:

I mean there are stranger dates I could go on, and with this at least we have a lot to talk about :joy::rofl:. Really though, good to have these in one spot so I don’t have to do some internet spelunking to find em.

He is fine with the questions, so long as the askers understand that he might take some time answering all of them because he has a job and a personal life outside of the forums :upside_down_face: :upside_down_face: :upside_down_face:

Really happy you posted them. Didn’t watch all yet but even the two I saw gave already a lot of useful information and food for thought. I indeed do not know more about genetics than standard highschool info but do really like to know more about it.

So let me start with the first question @t_h_wyman. You talk about bel complex and pied combo’s giving the risk of getting micro eyes in the offspring. Is this only in the double Homozygous form, like Bel-pied or is this risk also there in for example lesser pied or mojave pied? Or in Bel het pied? I was planning on combining them in pied in future but if this gives risk I prefer to avoid any problems for the snakes.

No rush to get the answer :grinning:… my pieds still have some growing to do. Already happy to get an answer before they are ready and this has been one in my mind for some time already.

Every double visual I have seen has had the issue. I have seen and heard reports of Pied Lesser and Pied Mojave having them as well, though in these the phenotype tends to be less pronounced. I have not seen or heard of the issue in BluEL het Pieds but, given the obvious synergy with these mutations, I would not be surprised if it were to happen.

I have a question relating to your explanation of Pastel with Gavin.

You talk about Pastel being a hypomelanistic trait, with it basically pulling back a few layers of melanin to reveal the colours beneath.

Would Banana be a extreme hypo trait or is there something else going on?
If so, what is the spotting about?

Piebald/albin/melan/leuci... "-isms", what do they actually mean?

Yes and no.

Banana, and any of the other T+ type albinos, are all different forms of hypomelanism. Which is to say, they all produce melanin to some extent or other but it is either at a reduced quantity, deposition, or display (finer points not needed for this conversation). So in that respect, they are the same

How they differ comes down to… Call it presentation. In my explanation for Pastel, I likened the melanin to being like a lacy doilie. Let me see if I can sort of redirect that analogy in a way that makes sense…
.
.
.

Instead of a doilie, instead imagine a fishnet stocking with holes about the size of a dime. Take that stocking and dye only the top portion of it with black ink. Pull that stocking over your leg. Take some scissors and, along the length of your leg on the sides, cut a few holes. Now… Get another stocking and repeat the process, cutting the holes on the new one to match the holes on the one beneath. Do that again. And again. And one last time but for this one, do NOT cut any holes.

Right about now you are probably asking “Why has Travis made me do this to myself” right?

Well, congratulations, your leg now looks like a ball python (sort of).

So how is this relevant to Pastel versus Banana?

With Pastel, the mutation changes the “size” of the holes in the fishnets, instead of being dime-sized they are now quarter-sized. This does not make a huge difference on the areas where there is no pattern cut because the overlapping layers do not line up perfectly so you stay looking mostly black there with occasional spots where the overlap is perfect and you get lighter areas. But on that last outer stocking, the larger holes means that the flesh colour of your leg is less obscured/more visible. And, by extension if the holes in the netting are half-dollar-sized (SuperPastel) this results in less overlapping and more light areas in the non-pattern areas and even higher visibility of the flesh in the cut-out areas

Banana (and the other T+ types) is different. With these, the mutation effects the step where you are taking dye and dying the top half of the stocking. In these cases, the dye has been watered down. So instead of being black, the dyed areas are some shade or other of light grey.

In both situations there is less melanin being presented, but the cause for each is different.

Make sense?

Also, you can go take off the fishnets now (or not, I do not judge LOL)

The spotting in Bananas is something specific to the mutation. For some reason or another, the melanin is being turned back on in small areas. There area a few ways this could happen and I have a suspicion as to what it probably is but I am hesitant to speak it aloud and have someone think I am claiming the idea as being ABSOLUTELY THE WAY IT IS and then spreading it all over FB and the like.

Strangely, it makes perfect sense and was a fantastic way of putting it.

However straight out of the gate you hit me with something I had never heard before, or maybe I just misinterpreted it…

Banana is a type of albino?

Do you believe this is something that happens individually during the development of the snake or is a genetic trait that can be line bred, such as “big spots” X “big spots” = huge spots.

I was just beginning to get comfortable aswel :joy:

Yeah, Banana can safely be considered as another of the T+ type albinos along with Caramel, Ultramel, Lav, etc.
.
.

Not something where you could breed for larger spots, no. If it is what I think it could be then it might be possible to select for animals that have more versus less freckling

I read the title and thought it was an auction…well then.

Travis is always a great wealth of information. I have listened to some, but was unaware of the CRISPR one. Always been interested in the potential of that. Looks like I got a couple to listen to tonight. Thanks
