bumble crossed with albino?!

spill the info, we've gone this far!:D


what 2 morphs do you want to pair up?:)

oh lol sorry i thought i posted it already i want a spider and pastel! :D

adi,
I wrote all this before you posted just a little bit ago. Decided to go ahead and post it anyways! ;) As far as which traits are dominant/recessive/co-dominant, it comes with time and study. Main thing to remember is - if the het form doesn't show, its recessive. So when you see het albinos, they look normal. If the het form looks different from the normal, and different from the monozygous (like pastels/super pastels), then its co-dominant (or incomplete-dominant, or....), if the het form and monozygous form look alike, but different from normal, its dominant (like spiders).

Here's the stuff I wrote earlier -

I started out writing a long description of dominant/co-dominant/recessive genetics. It got really unwieldy really quick. Are you in high school? If so, I highly recommend that you take all the biology/zoology/genetics classes that you can, and study and pay attention and learn genetics! Maybe get hold of a biology text book that is at the grade level that you are, and study the genetics chapter. At the very least, it will cover dominant and recessive traits, maybe not co-dominant. There's also incomplete-dominance and others as well. In the ball python world, the others exist also, but understanding dominant, co-dominant and recessive will get you a long ways. It won't matter if they are talking about eye color in humans, tail length in hamsters, or ear length in rabbits. Its still genetics. Be sure to learn how to use a punnet square to predict genetic probabilities.

I gotta go feed normals, spiders, pastels, albinos, het albinos, and het pieds now. ;)

Hope this helps,
Steve

right on steve! thanks! i am in high school and i will be learning about genetics in a month or two so i can get a head start! :D that acutally helped and made perfect sense! thanks again

Read that chapter NOW!!!!

By the way, I edited my post after you replied.

Have fun!

To get a better grasp about how traits are passed from one generation to another, you need to understand how sperm and egg cells are made, and what happens when they meet up first, so here's a good high school biology review of sexual reproduction (the process of meiosis, and fertilization)....

Most animals are diploid, meaning they have two copies of each chromosome (2n). Each individual chromosome can be carrying different genes, maybe even a mutant gene or two ;)) Meiosis is the production of gametes (sex cells), and ends with cells that have only one of the two copies of each and every chromosome (1n). When these gametes hook-up (fertilization) the egg takes on the chromosomes carried by the sperm and the resulting cell now has two sets of each chromosome (2n), one from each parent.

So why is that important in understanding how BP morphs are inherited? When all these animals reproduce, each parent only gives one of each chromosome, right?. In heterozygous animals (with one mutant gene and one wild-type gene), this may be the chromosome that holds the mutant gene, or it may be the normal chromosome, 50/50 chance. In homozygous animals (mutant or wild type) they can only give one type of chromosome, as both copies are the same.

With recessive traits, if there is a normal copy of the gene present, the trait will not be visable, as wild-type is dominant over these traits, but the resulting offspring will be a carrier for the trait, or a het. With dominant (or co-dominant) traits, the wild-type trait is recessive, and the mutant gene is expressed visibly in the offspring.

If you understand this info, and understand which traits are recessive, or dominant over wild-type (normal), you should be able to figure out the ratios for the resulting offspring of any pair of animals.

Hope this helps, and didn't give anyone flashbacks of bad high school memories. :rolleyes:

AHHHHHHHHHHHH GENETICS CLASSS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!: D



I acctually loved that class, it is just nice to know there won't be a test in two days on this post!!


~mike

wow thanks! this will so get me ready for future bio classes! lol you guys sure explain very clearly....thanks again everyone! you guys teach better than my bio teacher! :D

good explination. Here is a punit square

ill do this simple i'll use all a's capital A will represent normal and little a will represent a recessive trait (say albino)
mom's genes will be across the top, dads down the side
Mom will be homo for the trait, dad het
(ignore the dots, they're just to keep it lined up right)
...a ...a
A Aa Aa

a aa aa

The possible results are Aa, and aa
in the Aa ones the A (dominant trait, normal) covers the a (recessive trait, albino) . In the aa ones both genes are the recessive form, so the baby shows the trait. The Aa's cary the trait, and although they look normal can still pass the gene on (like the dad in this case)
