The reason for recessive genes not disappearing is because there is always a different gene that you can pass on through your offspring

Recessive genes
A trait can disappear in one generation due to a recessive gene being masked by dominant genes. When two carriers of the recessive gene have children, there is a 25% chance the trait will reappear in the next generation as the recessive gene is expressed. This is known as genetic recombination through Mendelian inheritance.
This phenomenon is known as dominance, where one gene masks the expression of another gene for the same trait. When an organism carries two different genes for a trait, one gene is dominant and determines the observable trait, while the other gene, known as recessive, is not expressed in the presence of the dominant gene.
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.

No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.

Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
NO, the traits do not disappear they are simply "masked". According to Mendelian theory there are DOMINANT (A) and RECESSIVE (a) traits. When Aa is present the recessive trait is masked therefore it does not show up. These are called alleles.

The dominant genes take over, and then the recessive genes hide away
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
