Platy Genetics

[sunpirate2u]

Ok so, I've been planing to post a question about platy genetics 4 a while now and I have little knowledge on the subject. so i need some advanced breeders to help me. One of the only things I know is that the mickey platy is based on the moon/crescent platy. Dont worry I learn very fast.

So, right now i have one high-fin mix male platy,

and a high-fin juvenil mickey mixed female, and they haven't tried to breed yet (ok i know the rule 2-3 females to a male but im waiting 4 my fry tank to cycle). I plan on getting about 3 more female soon (few weeks). So i have some questions:

is the high-fin gene dominant to a normal dorsal fin?

which colors r dominant to which?

is a mickey tail symbol dominant?

please if u have any other info i really would appreciate it. at this current time my brain can think of all the questions i had/have so i may edit this post later.

~thanks

The reason they might not have bred yet could be she is already preggoes.
Short fins are normally dominant to longfin unless both parents have the longfin gene.
There are no dominant colours so to speak. It depends on the parents. If you cross 2 reds you get reds. If you cross a yellow with a red you get some of each.
Mickey Mouse tails are no more dominant than any other colour pattern.
Platies are so inbred these days it takes a few generations of leaving them in a pond to breed freely before you even get close to getting original colour forms again. As a general rule you will get young that look like each of the parents and some that will look like a combination of both parents. A problem you might encounter will be if the female has been knocked up in another tank then she can carry sperm packets for months and use these to fertilise several successive batches. Thus you might only start getting young fish that have been fathered by your male in 6-12 months time. All the other young could be from any other male she has encountered before you bought her. When breeding livebearers most professional breeders try to keep the females separate from day one, or at least as soon as they can sex them. They keep them virgins so they have more chance of producing offspring from the males they are using.

I agree with colin, what he said is more or less what i would have

The mickey mouse patterning is moderately dominant, if you cross mickey mouse pattern platys with normal platys the resulting fry will most likely be wagtail platys although how large the wagtail pattern is depends on how pure the mickey mouse tail platys are- these are wagtail platys;

Preventing inbreeding by making sure the gene's pools of your platys are kept diverse is the best way to produce healthy robust platys, however it will be more difficult to produce platys which are guaranteed to look a particular way, however i always personally think that crossbreed pattern/color variety platys look more interesting and attractive, its nice to have some color/pattern diversity in a group of platys IMHO.
The pale yellow coloring on your platy can produce some really nice colors when you crossbreed such platys with different color platys- if you crossbred it with gray females, the resulting fry will most likely either be orange or a tan brown color, while breeding it with red platys will just result in females with a light shade of red or dark shade of orange. Crossbreeding your male with black and white calico platys will result in rather attractive calico pattern fry with some of the colors of your male in them (the red dorsal fin should be quite dominant in the male fry)- this calico platy in the link below was mostly likely a plain red platy crossed with a black and white calico platy;

"Blue" platys, which are basically gray platys with a metallic blue sheen ( [URL="http/www.faszination-lebendgebaerende.de...Blauspiegel.jpg"]http/www.faszination-lebendgebaerende.de...Blauspiegel.jpg[/URL] ), have quite a dominant metallic sheen on them, crossbreeding them with non-metallic different color platys will often result in fry that don't have the gray coloring but will have a good green or blue metallic sheen on them .
