double homozygus ressesive, How do most do it?

I was wondering how most people get em. I get that you start with a DH. But do you breed a DH to DH or do you breed a single Homozygus to the DH and hold back all the homozygus or.......

Well I'm by no means a genetic expert but DH x DH only gives you a very slim chance at hitting the double homozygous. If possible it would be best to breed a homozygous het x homozygous het. For example if you are trying to achieve an albino pied, breeding an albino het pied to a pied het albino ups your odds to 25% chance per egg.

I haven't done it yet myself, but I'd breed the double hets to each other. You'll have a 6.25% chance per egg of getting the double homo.

Breeding a dh to a visual you'd get some visuals 50% het for the other. That would mean a lot of hold backs to try to prove them out.

No matter how you do it, it's a long term project I think!

This is probably the best way, but a lot more expensive to start out I think. (I try to do stuff in the least expensive way!)

Well in a perfect world you could breed double homo to double homo (i.e. Albino pied x albino pied) but that sorta defeats the purpose lol. However if you can swing it you then get 100% albino pied. Wouldn't that be nice! Lol

Homozygous A X Homozygous B = Double Hets

Hold back a male DH and a few female DH raise them up and than do DH X DH and cross your fingers because it is a 1/16 chance to hatch a Double Homozygous ;)

Chances per egg of course.

I know the chanches are small I just didnt know if people do dh every time or try to prove out a homo A 66% b ect

both, do what ever it takes lol.

I start out with possible double het males to normals. I'll let you know how it goes in another 10 or 15 years, lol. Seriously, where is the fun in paying for a known shot at only 1 in 16 odds per egg when you could go with a cheap Hail Mary and decades of anticipation ?

Because im one of thoes people that like to control as much as I can. The less I leave to chance the better. Besides the question was more aimed for personal knowledge then a plan to attempt. Besides in 10-15 years the prices will have dropped so much that I could afford to just buy one. Look at the albinos

I'm shooting for an Albino Pied! The route I choose was:

Albino 66% het for Pied

1.5 66% double hets

My girls are too young this year, but I have been trying to breed my Albino boy to a het pied girl. He does not show any interest yet:(

If I produce any pieds out of my Albino x het female, I will keep them. I will know that they are 100% het for Albino.

I'm sure that there are better ways to do it, but this was the most cost efficient route for me.;)

I always ask myself these 3 questions:):)

1. How much $ you are willing to invest?
2. How patient you are?
3. How much do you like to gamble?

Well here's how we're doing a double homozygous:

We're shooting for Super pastel Hypos (granted, not double recessive, but still double homozygous).

We went ahead and purchased:
1) pastel hypo male
2) pastel het hypo female

This will improve our odds per egg (compared to a potential breeding of double hets) from 1/16 to 1/8. If we don't hit the super pastel hypo, we'll keep back a nice female if we get one, and keep trying.

By using a homozygous hypo male, we're guaranteed that any pastel or super pastel females we keep back will be at least het hypo, and will be worth pairing up in a few years to have more chances at the combo...if we have bad luck and don't hit it by then.

And since I'm very low on question 1 it works out well that I'm high on 2 and 3.

I finally produced an albino female in 2009 after only a single decade of work and she was also 33% chance het stripe but since I still couldn't afford albinos I couldn't afford to keep her. Selling her was a real shame as I had a good feeling about her pattern. I did keep two of her possible double het sisters though.

I appreciate the cost constraints and this could be a fun longshot project anyway but, until and unless you produce a pied you can't actually be certain that you have any male carrying pied genes. 5 x 66% double het girls gives you a reasonable chance with the females but I can't help thinking that it might have been worth your while investing in a male pied somewhere along the line, or better a female pied to go with the male albino 66% het pied tp produce your own double hets-at least you would know what the babies were then.

I agree:) but
By the time my girls are of breeding age I should have some pieds:D I have lots of other projects going and this is just a small one.
In my collection I also have:
1. Pastel Het Pied
1. Het Pied
1.1 Pewter 66% het Pied
.7 Het Pied females (not including my possibles)

It was more cost effective for me to go with het females because I have other males to prove out. You can get 4-5 het female hatchlings for the price of a female pied. I also chose the Albino male because its a lot easier to pick out a het Pied in a 66% het clutch than an het Albino.:D

I'm hoping to prove the Albino male out this year with one of my het females:)

It depends on how new the project is. I say that because the "homo A 66% b" animal you speak off came from a DH x DH pairing. If you are the first to try and make a double Homozygous Recessive animal, you wull be starting from scratch.

If I were going to invest in a double homo ressesive project, I would go with a visual het to a visual het. For example, an albino het pied to a pied het albino. Double hets, in my opinion, are not worth the time invested. The chances of producing a double homo from two double hets are extremly low, and all non-visuals will be poss het for both genes. Not worth it, IMO.

yea but if your the first to try the combo, you really don't have much of a choice but to do dbl het x dbl het because the visual hets don't exist yet.

Homo A Het B X Homo B Het A.

No one is selling Homo B Het A females that I've seen (I have seen an Albino Het Pied male for sale though). I figure there might be some for sale this summer but they will be pretty expensive.

I'm actually planning a different route, Super Pastel Pied male X Ghost Het Pied (or other recessive het pied, haven't decided yet). Hopefully by the time I can afford a Ghost Het Pied female and get her up to breeding size I will have already produced my own Super Pastel Pied male (have Pastel Het Pied male X Pied female going this year and kept a couple Pastel Het Pied females I produced last year so I have the makings).

Homo Pastel Pied X Ghost Het Pied = Pastel Pied het Ghost and Pastel DH

male Pastel Pied het Ghost back to mom (Ghost het Pied) = Pastel Pied Ghost :)
