Lookng for another morph

Hey guys, new to the forum here but not new to snakes. Tomorrow I'm heading to the SC show and looking to pick up another BP. Nothing too freaky, I was thinking about a Spider or a Pinstripe, add some dominant traits into my mix. Currently I have 0.1 Piebald, 0.1 Bumblebee, 0.1 Normal, 1.0 Albino and a 1.0 Pastel. Would either of the 2 I mentioned, in your opinion be a good match for my collection combo for breeding? And would you suggest a male or a female?

Also I'm still unclear as to how the recessive trait works, if I breed my male albino to my female piebald, will it yield all hets or will I get any visuals ie: albino piebalds?

Sorry for all the questions in one post but as you can tell by my sig I mostly deal in arboreal snakes and what you see is pretty much what you get with the parents.

Welcome to the forum. Both snakes mentioned in red are codominant, not dominant. Also...I would go with the pin. You can produce your own spiders with the bumblebee.

Hi,

Not officially so far as I know - there are rumours of a homozygous spider and homozygous pinstripe - but neither is said to be visually different from the heterozygous form so they are still considered dominant.

Unless you have read something we haven't seen yet in which case please share?

The text below can be applied to any simple recessive gene:
piebald, albino, axanthic, genetic stripe, hypo(ghost), lavender albino, caramel albino, etc.

this page may help you a lot. Pieds, or piebald is a simple recessive mutation. This means, that both parent animals need to have at least one copy of the gene in question to have the possibility of producing offspring that not only carry the gene, but display the trait that it carries.

Hets, or heterozygous animals, are animals that CARRY the gene but do not display it. They look completely normal. You can not tell which animals in a clutch are hets unless you bred a visual animal (in this case a pied) to a female. ALL the offspring produced would have one copy of the gene (in this scenario it came from dad) so they would be 100% het/heterozygous pied.

100% hets - animals known to be carrying the questioned gene.

66% hets - these animals are produced by breeding two 100% hets together. Once they are proved out by breeding, they either ARE heterozygous or NOT heterozygous for the gene in question. This does not mean that 66% of the babies will be pied/carry the pied gene/etc.

50% or possible hets - these animals are produced by breeding a 100% het animal to a normal animal. The babies have a 50% chance of carrying the gene in question. Like the 66% hets, these guys need to be proven to be het or not by breeding

I know a few years back, a lot of people incorrectly were calling any mutation with a visually distinct heterozygous phenotype codominant (even if there had not been a homozygous form hatched yet). That poster may have heard them called codominant in the past. Lately though, it's shifted to more of a "dominant until proven otherwise" mentality, which is probably a better way to go about it...
