You lost me....what you talking about Willis ? LOL :D
Would a gene that is not expressed in the heterozygous condition be recessive? If it is heterozygous then that means they are different such as Aa if I am correct. The A being dominant and the a being recessive. I think the expressed gene is always the dominant gene in heterozygous, so this leaves the recessive gene is that right?

I don't have a answer for you but I can remember studying stuff like that from a genetics class many many years ago. :D
Maybe this will help you.

FINALLY, a subject I can interact with. Here we go...These are two possible states of a gene for a diploid organism. Each gene is made up of two representative alleles - one inherited from the maternal source (mother) and the other inherited from the paternal source (father).
When a gene is homozygous, both alleles for that gene are the same (ie both the mother and father contributed the same version of the gene). When a gene is heterozygous, each allele is different.
Now, we must not forget about the third term of describing the genotypes, which, by the way, is hemizygous. Each has it's own place in determining a multitude of differences between dominance or recession of the genome.
"I think the expressed gene is always the dominant gene in heterozygous, so this leaves the recessive gene is that right?" Was, I believe, your real question. Answer, simply, is if you only have two factors (dominate or recessive) it would have to be.

A gun in hand is a lot better than a cop on the phone.
This question is answered by Mendel's 2nd Postulate: " When two unlike unit factors responsible for a single character are present in a single individual, one unit factor is dominant to the other, which is said to be recessive."
Brings back memories of the fruit fly days.
I thought that was correct, thanks for the help. I am in college and we have to learn all this in Biology and anatomy. Good ol punit squares. It is not as hard as it sounds
I teach genetics and your understanding is correct.
