Hypo's Is There A Science?

[eladidare]

ignore the criticism jaz, you know what your on about, most of these guys would of heard it of people or read it in books, its good to see someone like yourself figuring these things out for themselves...

[Jaz681]

thanks eladidare...
i just would like to know if what i think is right in anyway or am i off the beaten track?

Get your hands on "Origin of Species" Darwins renowned book. That is an interesting read, and read anything on Mendels.

Yeah you are on the right track.

If you are seeking anything in a species, the only place that the genetic code to express that is going to come from is the parents.

So if both your parents are striped, then there is a high percentage chance that you too will be striped. But that is without getting into the whole dominant ressesive gene thing.

Getting onto the whole hypo thing.

You can have either Hypo melanistic, or hyper melanistic, which simply means - reduced melanine (black) pigmentation and increased pigmentation respectively.

So in order to answer the question regarding whether something is hypo or not. You have to first look at what is "standard" HA.

Once you have established this, then something can be determined to be hypo.

Regarding herps though, there are differing grades of hypos, obviously a Grade 1 hypo is a complete hypo, i.e. has no black pigmentation. a grade 2 would be something that is reduced, but not completely.

well yeah.

hypers are obviously the opposite, rather than reduced, it is increased. Unfortunately, there are not enough of these around for my liking. But hey thats just me.

Isn't an animal completely lacking black pigmentation an Albino???
Then a class 1 hypo would be greatly reduced black pigmentation, but some present,
and a grade 2 hypo reduced, but not as much!!!???

according wikipedia

(very basicaly) albinism is the lack of Melanin pigment. So a lack of black and dark brown realy.

its too late for me to read any more but: http://en.wikipedia.org/wiki/Albino might be a place to start. i love wikipedia... even if you cant directly use it as a reference in an assignment...

You might find this genetics link interesting Jaz681 if you haven't seen it before.

Nope. A hypo means reduced black pigment. Something that has no black pigmentation is amelanistic. No melanin.

An albino lacks all types of pigmentation, not only black. An animal lacking all black is amelanistic (see above reply by me).

An albino lacks melanin, and red pigment, and brown pigment, and green pigment etc etc. For example.. A green tree python has no black pigment. It is green. But it certainly isn't an albino.

Yes you are correct, something with complete loss of black pigmentation is amelanistic, but as i said, a grade 1 hypo in the herp world is considered an amelanistic animal.

Though not scientifically correct, in the strict sense of terms. But it is how it is refered to in the herp world by those that sell hypos. Hence the use of "grades". Otherwise nearly anything could be considered as a hypo, so long as it didnt have as much melanin as the direct parent .

But yeah, know what you mean, not every one can understand nerd though

thanks ppls. lots a bit of info and what i wanted... a discussion

how can albino be a lack of all pigment? Albinos still have yellow and reds, Leucistic animals are pure white altho they still have black eye pygment. I did look up amelanism vs albino and it says albino lacks all pigment but then why do albino's still have yellow and reds?

[TrueBlue]

amelainistic is another term fo an albino in reptiles, they mean the same thing just different word.
Albinos donot lack ALL pigment at all, just melainin.

[hornet]

that what i always thought tb but this site says otherwise

[SlothHead]

Yeah know what you mean there Hornet,

Albanism is a lack of melanin pigment, which is more applicable to humans etc.

But true albanism is as that site suggests
