Now!... To Cut A Short Story Long.....

[Ludwig Venter]

Ye all know, I have 1000's of guppies coming from a variety of parents... (about 10 or 12 individuals of 'em) including "halfblacks"; "Tuxedos";..Red tails, leopards etc...etc... etc, and the lot of 'em inbred to produce some interesting offspring in LOTS of generations over the past 15 years.....

Now, I have consciously decided to bring in some new blood, and got meself a fluorescent Blue and a striking blond red... 1 male, and 3 females of each.

These were kept separately from the rest, (they have lots of fry which I'm gonna keep separated as well), but in the meantime, I also secluded 15 of my mixed breed females, to drain them from any fry they may have carried for at least 6 months.

Subsequently,..... I introduced them (the females) to my new fluorescent Blue and a striking blond red males... (2 males to the 15 females).- having removed all the fry they had during the past 6 months. Now, I know when they get pregnant again, it'll be from my new stock...... I am waiting anxiously for the fry from this development, and it seems that all the females (15 of 'em) are pregnant!

When this happens I would love to see pics of the fry. I love my guppies!

I would love to know more about playing around with genetics etc,.... but with me it's a case of "come what may".... it might turn out to be a hit, or I may produce some awfull looking monsters.....Why not..... (everybody) post some pics of your own Guppies, While we wait for these to develop..... or can anyone "predict" what I can expect to get out of this?

Anybody knows about genetics..... at the end of the day, what can I expect,,,,,

To talk guppy genetic's you need www.guppydesigner.com
Philip know's a thing or two but he make you pay to get access to the main part of the site!

I was a member for a year but not join again.

I'm sure we have a coupla experts on our own show..... Anybody???......

if the parents are some form of hybrid. you may get some recessive genes in the mix at some stage. its complicated to explain but once you have the hang.

i will simply explain a few things

a pure red blonde with a pure red blonde would have red blonde babies.
but say a red guppy (that were a hybrid with blue recessive genes) and another red guppy with blue recessive genes were to breed these would be the out comes ( in a table)

guppy 1 (genes Rr (big R is dominant (red) little r is blue(so the red guppy carries both genes))
guppy 2 is the same

so you have Rr breeding with Rr put them in a table:

X...R...r
..l--------
Rl RR...Rr
..l
rl Rr....rr

so you would have 25% of the brood with RR genes for colour so would be red because red apears twice in its coding for colour.
50% of the brood would also be red but would carry a blue gene (this didnt show because red is dominant over blue)
25% would be blue because they have rr coding for colour, both genes are recessive but seeing as there are only two genes for everything (one from the mother, one from the father) blue is shown because no red gene is present.

hope this makes sense and i hope the table works.

of course the red being dominant is for example and i dont know if its true, the only way to find out is to get two PURE guppies of either colour and breed them and note the results.

Protigae Truckasaurus!!!!.... It does not make sense,..... But I believe you!

lol, maybe helter skelter can clean it up? im not good at explaining things without confusing myself

 

[helterskelter]

The thing with guppies i's not just one thing that results in the colour their are many gene's that affect the colour, yes once you get a line fixed they breed over 90% true but u always get rejects

Here is a platy x sword pic the explain's the basic side

Ah!!!!!...., That explains it...... Now if the Platy is called Sarah....... The male sword is called Joe??? (only joking - of course),... but thanks for your effort.

ok lets look at albino as this is easy to take in

you have 1 fish with albino (aa)
and a normal fish (NN)

and you cross them

NN x aa
resualt is all of spring expressing the normal colour but carrying the albino gene

Na



Next you cross the F1 of spring

Na x Na

Resulting in

• 25% NN (Normal)
• 25% aa (Albino)
• 50% Na (Normal but carrying albino gene)

Then if you have 2 pairs of gene's it results in 6-8 variations and builds up this is why it's so diverse and almost impossible to track.

When fixing a line it's handy to some times have a line of guppy called pingo
The females carry almost no colour genetics so crossing them back to a random male will carry most of him genetics in the F1 cross
But their rare fish to find.

Ok dose that help any more

that makes more sense than my explanation!

if u want to try to get the resualt quicker u can do back crossing (son to mother for example)

mum is aa
son is Na

now u cross this and you get

• 50% aa
• 50% Na

Which give much better odd's but only if your working with good healthy fish.
