Genetics Question

[RoyalHouseMorphs]

I'm really confused right now as to how 3, 4 or even 5 gene animals happen. Everywhere that I have read about genetics they all say that the baby receives one gene from the mother and one from the sire.

Anyone able to enlighten me? Or talk a bit deeper into the genetics?

its really easy.

lets say you breed a mojave enchi ( = mochi) to a cinnamon pastel (= pewter).


Now the babies have 50% chance to get mojave from dad, 50% chance to get enchi from dad, 50% chance to get cinnamon from mom, and 50% chance to get pastel from mom.

win all 4 coin-flips and you get a 4-gene mojave enchi cinnamon pastel. lose all 4 coin flips and you get a normal. most babies will get two of the genes because thats statistically most likely, but anything between 0 and 4 genes can happen for each baby in this case.


its only when you want a visible recessive, like an albino, or a super-form, like a super pastel, that both parents really need to contribute one copy to the baby each. And when you breed a super form, like a super pastel, to anything else, then 100% of all offspring will get one copy of pastel. but different individual genes, if they are not allelic / part of the same gene complex, these get passed on randomly.


by keeping the snakes where the odds are really great and that got an above average amount of genes, and then breeding these, you can ramp up the number of genes over the generations. You breed single-gene BPs together, hit mostly single-gene BPs, but also some normals and some 2-gene BPs. You keep the ones with 2 genes, breed these, get mostly 2-gene snake but also some with 1 gene or 3 genes, maybe you luck out and get a 4-gene BP. You keep the best ones with 3 or 4 genes, breed them, and now you can get some 5-gene stuff or even 6-gene stuff if you get lucky, of course you will mostly get BPs with 3 or 4 genes.

Some different mutations are housed on different alleles. So there are small individual coin flips.

Different alleles (different version of the gene) are located on different loci (location on the stand of dna). So one gene could effect one part of the strand of dna while another effects an completely different gene at a different location within the strand.

Everywhere that I have read about genetics they all say that the baby receives one gene from the mother and one from the sire.

That would be wrong, the baby receives multi-thousands of genes from the mother and the same amount form the sire. What you are reading really meant, the baby receives one gene from a locus from the mom and one gene from the same locus form the dad, giving it the pair of genes that sit on a locus, but it does this for multi-thousands of loci.

Thanks guys! Cleared that right up for me!
