Genetics Question...???

[JungleRob]

On a side note, punnett squares also show that for humans, when reproducing, the chances of getting a girl are 50%



Although, those sperm/egg diagrams are incorrect. Each reproductive cell contains both set of chromosomes.

PMSL! Are you for real?:shock:

What's the other 50% boy?:lol:

In one of the discussions about a possible new albino mutation, Doc mentioned that he sold a few early hets (or possible hets) as normals because he didn't want to euthanise them. In that case they were same price as normals. I would have no desire to pay a higher price for a 2/3 chance that an animal was a het. I would be royally peeved if I spent years feeding and then trying to breed an animal, only to find out I was unlucky in the genetic lottery!

And you make a really good point pythonmum. Even though punnett squares say 50% 25% etc.. there's no guarantee that a hetero will even produce an albino. You could keep going and end up with nothing, or your hets pass their breeding stage and you could be left with all "normies" 0.0

Just compare my post above about girl babies vs boy babies, and those mother that have 7 sons for example.

I have one query though. What of the albino aa and normal AA?
Would it not be displayed as -

50% aa
25% AA
25% Aa ?????.
Is this correct?
Cheers

Another thing quickly, there is no way of actually knowing which is Het or normal either. You could pay more for nothing.
Even Het by Het still produce 25% normal. I have seen olive pythons sold in this manner and the price was far from fair. The only way would be to have the whole clutch and and breed all the animals to see what comes later. This process will take years. There is no way we should be paying more for an animal that just may or possibly be Het. Feeling Lucky?

Male Albino Darwins are worth more because they can cover a number of females thereby spreading their albonism further. If you put an Albino Male over say 6 possible het females you should get the same offspring as 4 clutches from het females plus two extra clutches of hets.
On that basis they are worth about the same as hets less a bit for the hassle. It depends upon how much space you have.

I never understood why Simon sold a lot of males and not many females. From a business sense point of view, selling females would have limited the amount of hets and therefore albino's hitting the market.

Only problem is that he'd have to retain dozens of useless albino males...

 

[Nagraj]

how much would people think possible hets should be worth and should there be a difference between male or female possible hets in price just out of curiosity??

I made the following offer on a possible het for albino and it was rejected by the seller.


I pay twice the going rate for a normal animal. (in this case $800).

When I breed the animal with a 100% het (which I already possess) .....
1. If there are no albinos the deal is finished.
2. If there is 1 albino it is mine and the seller can buy their pick of one of the possible hets at the rate for a normal animal (ie. $400).
3. If there are two or more albinos the seller can purchase one at a discount (say 20%)
or choose option 2.



The seller suggested they could just keep it and do the same themselves and that's fair enough.

Don't forget Junglerob that those percentages don't work on exactly to that particular clutch. There is 50% chance of albino to 50% chance normal. It is no guarantee an albino will turn up. It guarantees the chance of the genetics not the numbers in the clutch. However, as they would all be carriers it makes your project just that little bit more interesting.

AA x aa will give

100% Aa so all would be Hets.
