genetic geeks

okay guys I'm having a brain fart on triple hets

what would you get if you bred triple het together?

albino, axanthic, clown just examples

and also quad hets

albino, axanthic, clown, lav

I went to the genetics wizard however the decimals are throwing me off.

thanks

A simple way of looking at it is to break it down into its parts.

For example breeding 2 triple hets together (albino axanthic clown)

25% will be albino
25% will be axanthic
25% will be clown

1/16 will be double homozygous
1/64 will be triple homozygous
Only 1/64 should be COMPLETELY normal (not heterozygous or homozygous for any traits)

Every animal will be 66% het for the traits it is not homozygous for.


To me that is the most simple way of viewing it.

what about the double homos?

I'm not sure what your asking but all double homozygous from the above pairing would be 66% het for the 3rd trait.

I guess what I am asking is:

1/64? will be triple homo
1/25? will be albino 66%pos for clown and axanthic
1/25? will be axanthic 66% pos het albino and clown
1/25? will be clown 66% pos het albino and axanthic
1/12? will be double homo albino clown 66% axanthic
1/12? will be double homo albino axanthic 66% pos het clown
1/12? will be double homo axanthic clown 66% pos het albino
etc.

don't know if the probabilty is correct

If you have a core understanding on how to use punnet squares in double genes, you will be able to replicate that for as many genes as you want.

The chore is to practice that over and over until you can easily figure out a punnet with double or triple genes. :gj:

I would advise reading NERD's walkthrough in genetic punnets, and just practice practice practice.

That's the best way I learned it, and it's really easy to do triples and quads once you have the punnets figured out. ;)

I have a pretty good idea when it comes to double recessive but not on triples or quads

Are you good with punnet squares? I think that's probably the easiest way to visualize the probable genetic make up of the offspring. For triple and quad recessive, you just keep adding them in.

Odds for having a homozygous animal are single recessive is 1/4, double is 1/16, triple is 1/64, etc etc. For any trait its not homozygous for it has a 2/3 chance of being het for it.

So lets say you crossed two het clown, ghost, xanthic together. There would be 1/64 chance of getting a animal homozygous for all three. There would be a 1/16 chance of getting one that was homozygous for two of the genes, and a 1/4 for getting one that was homozygous for at least one of them.

So lets say you got a clown from that pairing. That clown would then have a 2/3 chance (or 66%) of being het for ghost OR xanthic. It would actually have a 4/9 chance of being het ghost AND xanthic.

But if you do the punnet square, these ratios will make a lot more sense...

Have you written out a punnet square with double?

The same idea applies, you look at all possible outcomes for the genotypes, throw them into a square, and cross.
