I ask this question with two purposes:


1) to obtain a clear explanation of the meaning of "recessive genes".


No such thing.  You want to know the meaniing of "recessive mutation".
It has a very simple definition and is posed in classical genetics.
The phenotype of the heterozygote (mutant versus wild-type) is
wild-type.  If the phenoytpe were that of the homozygous mutant, then
the mutation would be dominant.  Most of the answers in this thread
confuse underlying molecular mechanisms for this result with the result
itself.
