Is Miami Phase a simple genetic trait

wombat Sep 10, 2004 12:29 AM

Is Miami Phase a simple dominant or recessive allele, or is it a more complex expression of color tonalities?

Are there infinite intermediate colors between Normal/Miami or is it an on/off trait?

Thanks, just wondering what a Crimson Miami x ?Snow? (or something else with a heavy load of recessives...) cross might produce...

Miami is more of a line-bred thing. Something cannot be 'het for Miami'.

As for what a Crimson miami x snow might produce... well, a Crimson is a hypoA miami, so you'd get normals (some with a more miamish look) het for amel, anery, and hypoA.

That's not exactly accurate. While it is true that it is unfortunate that the name "Miami phase" was chosen to describe the animals in question, that is exactly what happened when Rich Z. promoted the color phase he found in the Miami area.

The color phase, as defined now, is identified in animals that have red-brick saddles on a gray-to-silver ground color. The best examples will have little to no yellow/orange coloration at all, and many people prefer the best animals to have thick black outlining around the saddles.

The Miami phase corn is every bit the color phase as is the Okeetee phase corn. I dislike the use of locality names for color phases as much as the next person, but saying they do not exist under those names is like everyone trying to ignore the 400 lb. gorilla in the corner of the room. It ain't happening.

Finally, Kat is right (as usual!). The Miami phase is a line bred effect and not the result of a simple recessive trait. An animal cannot be het for miami anymore than one can be het for okeetee. Both color phases are merely variations of normal, which may or may not have any links to any specific locality, regardless of their names.

Hope that helps a bit ...

Here is a pic (a really terrible pic, sorry) of the guy in question, he was sold to me as a Crimson Miami possibly het for Bloodred.

If I understand right, at its simplest, breeding this snake with a female snow would result in an F1 generation with various intermediate colorings between normal and Miami, but all het for AneryA, Amel, HypoA, and some possibly het for Bloodred... and the F2 generation would be a very mixed bag...

What happens if you have HypoA and Snow (Amel plus AneryA) at the same time? Or Bloodred and Snow? What would the phenotype look like?

Now it seems likely to me that this male Crimson Miami may or may not be het for some other traits, ditto the Snow, so if the F1 generation comes out expressing some recessives then I won't be surprised!

it seems that a silver/gray ground color is a miami PHASE ,but the miami locale is often interluded w/ yelloow neck colors , BTW i live in Miami.the ultimate Miami is to achieve that ground color.what i am saying is that only one in ten Wild miami would be the quoted Miami Phase Selects. if you look at the post above by me is a C.Cane x Crimson that produced Miami phase whether they are true Miami lineage is ? OH WELL i wouldnt call a miami phase an F- regulated,Miami locale.........Chris....the pic is an unrelated CC x Crimson L8r.........which are supposide miami lineage. WOW stick a fork in me, im done
