Boa eyes

Hi everyone
Does the colour of boa eyes give away there locality,species or morph or is it a case of you get what your given by parentage
Most of mine have got white in there eyes and my adult albino has obviously got the pinky/red eyes. It my other adult boa has got pretty much black eyes and can hardly see any dilation at all
Just wondered wether the eye colour gave anything away

Same like in humans, eye color is part of your genetics with dominant and recessive properties. F.e. 2 parents with brown eyes can still produce a child with blue eyes if both parents carry the gene for blue eyes (which is recessive). So to actually get an idea about "what comes out" you need to know where the parents came from, and their parents, and so on, to give you an estimation of what will be.

But there are certainly morphs specifically taken eye color in account (ie some spectacular blue or red eyes), don't think it tells you anything about locality or species unless specifically mentioned in the name.

Thanks for that trd
I thought it was that I know the longicauda lazer eyes are just from them just wondered wether there was anything else in it
Was told sometimes in some jungles there are visual markers in there eyes that the breeders look out for

I don't think any of the locality eyes carry over when crossed, and I wouldn't rely on eye color to identify one, either.

SUPER jungles have odd eyes, which is one of the ways to identify them, but I don't think there's any markers in the eyes of a heterozygous jungle. You can immediately tell a super jungle from a regular jungle.

Thanks for that bsg much appreciated
Was just curious wether there was anything in the eye colouring with genes or locality
Cheers

I thought jungle was Co-dom/incomplete dominant.. like a hypo, no hets... unless you class the normal jungle as a visual het.

And that's about my total limit of knowledge on morphs,

Heterozygous just means it carries one set of a gene. I used heterozygous to try to get past the connotation "het" has in the reptile community, of being an otherwise normal snake not showing what it's het for. Yes, jungles are co-dom/incomplete dom, but a single-gene jungle is still technically a heterozygous animal. Super jungles are homozygous, because they carry two sets. They're just usually not referred to as hets by keepers/breeders.

I always wondered how people know an animal is heterozygous (or het) without DNA analysis because technically both a het and a normal look the same, well, in most cases (there are a few exceptions).

If you breed a recessive morph to a normal animal, all the animals will be heterozygous. Because, very simplified explanation!..

Imagen a baby being build out of gene sets... Each set determines a certain aspect of the baby (colour/patterns whatever)

- For each aspect of the animals looks, the baby will receive two copys of each gene.. One from mom and one from dad, forming a set....
- A weak (recessive) gene means, that BOTH genes in the set need to be the same for the animal to show the effect. (So 2 albino genes, means the animal looks albino)
- If one of the parents SHOWS the effect, it means it has the double set.
- Each parent gives a copy of one of their genes of each set to the baby, hereby the baby will Always get the albino gene from the albino parent. If the other parent gives a Normal gene.. This animal will be called Heterozygous. 'gene carrier'

This is also why there are 'possible heterozygous' animals if you breed 2 Heteros together. Sticking to the same example.. They will both have One albino gene and One normal gene.. Which one they will give their baby is random.. So some babies will both get the albino gene from mom and dad, others will get one, some will get none.. Since the One and None do not show any physical differences, they calculate how big the chance is that the baby got a least one gen (this would be called 66% poss het) You can only 'prove' them out by breeding them.

I once wrote a long in detail article explaining snake genetics sort of this way(more with pictures), if there are people interested I might rewrite it (lost it)

that makes sense
thanks for that
