When Do You learn This Stuff?

    I just watched a khan academy video on the difference between a gene and an allele. In the comments, someone asked when you learned this. One person responded 7th grade and another 10th grade.

    Things sure have changed in the last 50 years.

    And I still don't know what an allele is. For example, if I am A T at a specific point on a gene, is the allele the position I am looking at, the value, or both values?

    1. An allele is one of two or more alternative forms of a gene that arise by a quantum mechanism/mutation and are found at the same place on a chromosome. Huck its OK not to know. The alleles can be A or T so that what the environment your in will determine which one is expressed and the junk part of the DNA controls the program of expression. That is why calling it junk is crazy. It is the key piece of how DNA works.

    I still don't quite get it. Let's say I get A from mother and T from father. What is the allele?

    Is an allele on 1 strand? So if I am AT, is that an allele pair?

    They are both genes with slightly different codes in them.
