Genetics?

i have never been able to understand all the genetics involved with these snakes and have not been able to tell what all this het stuff is about. And can a snake be het for more than 1 trait. and how do you try to predict the possible outcomes of your snakes offsring fir both genotype and phenotype?
 
snakes can be het for multiple traits.

het means that a snake is carrying a ressive gene. this happens when only one parent is expressing that particular gene. If the parents are het for the gene, then you will only get a 50% chance of passing that gene on to the offspring.

Example 1:
Father - Snow - Homozygous Amel and Anery A
Mother - Normal
offspring will be 100% Normal het for Amel and Anery A

Example 2:
Father - Normal het Amel and Anery (snow)
Mother - Normal
Offspring - 50% Normal and 50% normal het Amel and Anery A

Example 3:
Father - Normal het Amel and Anery A (Snow)
Mother - Normal het Amel and Anery A (Snow)
Offspring -
9/16 Normal 66% poss.het. Anerythristic 66% poss.het. Amelanistic
3/16 Anerythristic 66% poss.het. Amelanistic
3/16 Amelanistic 66% poss.het. Anerythristic
1/16 Anerythristic Amelanistic

If you follow this LINK You will find an online genetics calculator. As long as you know what the genes you are dealing with, you will be able to predict what you might get.

Hope all this helps.

Just being picky, but that's technically incorrect. Heterozygous means that there are dissimilar alleles at any given locus. The gene being recessive, dominant, or codominant has nothing to do with heterozygous.
 
thanks for the correction. I said what I said to keep it simple beings they were already have problems understanding the genetics.
 
Thanks for all the help i can understand it a little better and the Link to the calculator thing really helped except i don't know what trait albino is under it but anyway thanks everyone
 
Albinos in the Corn world are called Amelanistic. They lack black pigment and are shades of red or orange as a result.

If you're looking for an all-white Corn, that's a Snow, which is a combination of Amelanistic (lacking black pigment) and Anerythristic (lacking red pigment).
