Genetics inquiry re: striped BCC

I am adding a male striped Guyana BCC to my collection next week. The seller says that the striping is believed to be genetic. If I were to successfully breed him to a normal Guyana BCC female, what percentage of the newbies would show the striping trait, if it proves out to be genetic? Hets? Thanks in advance.

If it is genetic whether the trait is Dominant or Co-Dominant or even recessive.

Dominant - Most or all with have some form of tail stripping/ reverse stripping.

Co-Dominant - Half will show the trait.

Recessive - There will be percentages of hets in the litter but will look normal.

Thanks for the reply. I guess we'll have to find out next year as he's still got some growing to do yet. I'm not gonna rush him. I'd like to have this beauty around for a very long time to come. He also has some striping down the top of the neck as well as the reverse striping, if that is any indication. Take a look. What do you think?

This is a very interesting subject.

The striping trait in boas is codominant. Simply put, this means: the allele that causes the trait will be expressed differently in the various forms. The homozygous form will look different from the wild type (obvious) and the heterozygous form which has traits from both will be different as well.

The easiest way to think about codominance is as a "blending" of the alleles.
Two genetically striped animals bred together will produce striped babies with various degrees of striping.

In your case, breeding your striped Guyana to a normal, you will receive 100% het animals. If the normal is carrying a codominant trait that interacts with the striping allele, then you will receive a mix of these traits.

There are different versions and variations of striping in boas. It is uncertain just how many alleles are at work here. You can see variations from simple connected saddles to full body striping and everything in between.

By the way, it is unknown whether the reverse striping is a codominant trait. As of yet, it has not been proven out. It appears to simply "pop" up in litters.
I have produced a few over the years, but without any real consistency.

Here's a couple of pictures for your viewing enjoyment. These animals were the result of a het to het breeding in 2003. I hope to be reproducing this in 2005.




I hope this helps. If you have any questions, feel feel to ask.

but you still have an awesome looking male whether its genetic or not. Mike , I need to shop at your place more often.

Thanks guys. Your information has really helped me to understand things a little better. Mike, Don't forget about me when you produce those stripes.

Don't forget me when you drop some some of those black tail boas.
