hypo genes

nuno · 10-24-02, 11:09 AM

I have been reading some books and wanted to ask if anyone could tell me if you take a Columbian red tail and a Hogg island Boa and breed is that how you get a Hypo or is it simply a Hybrid ? Just wanted to know how some people get this hypo gene bred into thier collection, also how can you tell if the species has this gene?

Please understand that I haven't found any books yet on the different type of genes and what the definitions are. I am not trying to breed but want to become somewhat knowledeable on the different types of genes and phases.

If anyone knows of a website or has any info on my question please help.

Thanks, Nuno

You are correct in your assumption that a hogg X Columbian would be a hybrid. It is a intergrade since both are BCI. The hypo gene is a specific gene just like albinoism. If you can get a copy of Dec. 2002 issue of reptiles there is an artice about samon boas. One of the types of hypo. It is written by Rich Ihle the founder of the line. Here is a web site that lists most of the boa morphs out there. Boa Morphs
Good luck with the study. Hers is another site that has genetic terms and definitions.Gecko genetics page

Thanks I will read all of the info on that site tonight.

Just thought that Hoggs have a natural hypo gene when bred to a redtail this would exercise the hypo gene and the offspring would be carriers of the gene.

Yes hoggs are a natural hypo, but they are different from Columbians. The biggest problem is the taxonomy of boas. Both the BCC and BCI have huge ranges and boas look different in different regions.

How can it be a hybrid (by scientific definition) if not only are Hoggs and Columbians the same species, but the same SUB-SPECIES??!!! Hmmmm......

I was trying to not confuse someone. I said it was an intergrade. But if the boa genus gets cleaned up then it would be a hybrid. It is a island species that has no change of breeding in the wild with a columbian. So alot of people would consider it a hybrid.

Jeff_Favelle · 10-24-02, 07:49 PM

Right, I was just messin' with ya. I mean, by the scientific definition of a "species" corns and kings should be the same as they produce fertile offspring.

Ok, back to the Hoggs; if they occur only on an island, wouldn't they be extremely succeptible to genetic drift, bottlenecks, and inbreeding? Maybe its a GOOD thing that they are being "crossed" out?

Jeff I am going to duck now. So that the splatter does not hit me. LOL

Lol .. no kidiing .. the backlash from that one could be painful

nuno · 10-24-02, 10:17 PM

I will now list a few words can you descrice these words

1-melanistic
2-Amerytheristic
3-melanistic
4-axanthic
5-hypomelanistic
6-Heterozygous

Hogg Isles in the wild are rapidly becoming extinct. Hoggs, show very different colouration and size differences as compared to columbian BCI and central american BCI. Outcrossing does not do them any good, but dilute the lines. Similar to rosy boas. These animals are so inbred in the wild, that the bad traits have been mostly filtered out. It's up to us, to keep Hogg Isle bloodlines pure.

Now, don't get me wrong, I love hybrids, I have a few, but there are times when hybridizing or intergrading does more damage than good.

Bryan Self · 10-25-02, 12:16 AM

I will give it try for you.
melanistic- melanin is dark brown or black pigment so that makes this a very dark animal.
Amerytheristic- I am guessing this is anerytheristic. This is lacking red pigment.
axanthic- Lacking both red and yellow pigment
hypomelanistic- Lacking black pigment
Heterozygous- consisting of dissimilar parts. This is easier with an example. For any ressive trait both alleles must be the same for the trait to show. You get one allele from each parent. So breeding any ressive trait with a normal animal you get 1 normal allele and 1 ressive allele. So you have a het(hetrozygous) for the ressive trait.
Hope this helps

Ha ha, we're probably going straight to he!! just for TALKING about it, ha ha!!!

Jeff_Favelle · 10-25-02, 12:23 AM

Why does it matter if we keep the lines pure? Its not like they are going to be released back into the wild anyways? If we're gonna domesticate, we might as well do it.

I would never breed a Hogg with a Red tail but since I am not familiarized yet with all the terms, I just tried to make a stupid guess. I read that a Hogg is a natual hypo and some Red tails have really nice pink on them I just thought that the light pigmentation of the Hogg and the pink in the Red tail that would be nice. I heard of blue phase Hoggs and just wanted to guess how sme combos are made, by the way does anyone have any blue phased hogg pics? or know how you get this phase?
Bryan good stuff!!!
