*The snake in the image above is not the exact animal you will be ordering. You will receive a representative of this morph that will look very much like this picture. **If you purchase a snake that is heterozygous (hetero)(het) for a particular trait, the snake you will receive will not resemble the recessive trait phenotype pictured above. For example, an amelanistic (amel) corn has shades of red with red eyes, but a het for amel is only carrying the hidden gene for producing amel corns. The het in this case will look like a normal corn with shades of black, brown and tan, and dark eyes. When the het amel is bred to another het amel with the same gene, or with the homozygous amel, you should get some amels. By breeding a het amel to a het amel, you should get approximately 25% amels. If you breed the het with an amel phenotype, you should get approximately 50% amels. ***Like hets, if you purchase a snake that is possible heterozygous (pos het) for a particular trait, the snake you will receive will not resemble the recessive trait phenotype pictured above. Using the amel model, if you breed a corn that is het for amel to another corn het for amel, you should get 25% amels. Among the other 75% that are normal looking, 1/3 will not carry the amel gene, and 2/3 will be het for amel. In other words, approximately 66.6% of those normal looking corns will be het for amel, but you cannot visually discern which ones. Normals from het to het pairings are called 66% pos hets . The only way to discover which ones are het for amel is through breeding trials. If you breed a normal looking corn (het for amel) to a normal looking corn (not carrying the amel gene), you should get all normal looking corns, half of which are het for amel. You would call all those babies 50% pos het. |
