Breeding Genetics Question

krresellers Aug 10, 2007 06:58 AM

My partner and I are thinking about purchasing the following for breeding
triple het stripe sunglow Female to a
Albino Jungle Male

And the other pair is Albino Kahl Female to a
Hypo 100 Het Albino Male

Can someone tell me the what type of babies I would receive. i want to make sure we figured it our correctly.

Thanks in advance.

PS is there a good site that explains this.

Thanks

Geneticswizard.com is a pretty good place to go you just need to know how to put the animals in...here is what you would produce with the first pair...this site really breaks it down...

Lets break this down to the actual genes involved. This will be my best guess as to what you actually have. I am making some assumptions here.

Assumption 1: All the albino mutant genes are Kahl albino, which is more common than Sharp albino. Mixing Kahl and Sharp albinos is believed to produce normal looking snakes. So if this assumption is not correct, there would be fewer albinos than expected (probably no albinos at all).

Assumption 2: The hypo gene involved in the two matings is actually the salmon mutant gene, which is dominant to its normal version.

Assumption 3: The jungle has a gene pair containing the jungle mutant gene and the normal gene. The salmons have a gene pair containing a salmon mutant gene and the normal gene. This is the most common arrangement. By the way, the normal gene paired with the jungle gene is not the same as the normal gene paired with the salmon gene.

Albino Jungle male: Two Kahl albino mutant genes. Jungle mutant gene paired with a normal gene. Normal genes where the female has her striped//normal and salmon//normal gene pairs

Triple het striped sunglow female: A striped mutant gene paired with a normal gene. A salmon mutant gene paired with a normal gene. A Kahl albino mutant gene paired with a normal gene. This snake is salmon but is not striped or albino. Normal genes where the male has a jungle//normal gene pair.

This is a four gene pair problem, fairly complicated.

Result:
1/8 salmon jungle Kahl albino
1/8 salmon jungle heterozygous Kahl albino
1/8 salmon Kahl albino (sunglow)
1/8 salmon heterozygous Kahl albino
1/8 jungle Kahl albino
1/8 jungle heterozygous Kahl albino
1/8 Kahl albino
1/8 heterozygous Kahl albino (looks normal)

In addition, all the babies have a 50% probability of being heterozygous striped. In other words, you can expect half the babies to be heterozygous striped and the other half to have a pair of normal genes instead. You just can't tell which is which.

>And the other pair is Albino Kahl Female to a
Hypo 100 Het Albino Male

Hypo 100 Het Albino Male: Hypo is often a synonym for salmon. Most of the salmons for sale have a salmon gene paired with a normal gene. And most of the het albinos have a Kahl albino mutant gene paired with a normal gene. If this snake is het for the Sharp albino mutant gene, then you will not get the results given below.

Albino Kahl female: Two normal genes corresponding to the male's salmon//normal gene pair. A pair of Kahl albino mutant genes.

This is a two gene pair problem, relatively easy.

1/4 salmon albino (AKA sunglow)
1/4 salmon (AKA hypo)
1/4 Kahl albino
1/4 heterozygous Kahl albino (looks normal)

By the way, the Blue Genes site is the best I know of for learning the rudiments of genetics. It misses a few shortcuts, though.

The Genetics Wizard is also good.

Thank you Everyone, I was close when I calculated it.

You were correct the snakes are kahl trait not Sharp.

Sounds like thye will produce a great group of snakes.
