Recessive alleles seem to vanish in some generations and reappear in later generations because they are masked by a dominant allele.
What are recessive alleles?
A recessive allele is a form of genetic coding that does not produce a phenotype in the presence of a dominant allele. The effects of the recessive allele are concealed by the more dramatic effects of the dominant allele in a dominant/recessive connection between two alleles.
What are dominant alleles?
A dominant allele is a gene variant that causes a certain trait even when other alleles are present. A functional protein is often encoded by a dominant allele. Because one copy of the allele produces enough enzyme to furnish a cell with lots of a specific product, the allele is dominant.

what are Recessive alleles?
In genetics, recessive refers to the link between an observed trait and the two inherited variants of a gene associated with that trait. Individuals inherit two variants of each gene from each parent, known as alleles. The alleles of the trait-causing gene are the same in the case of a recessive trait, and both (recessive) alleles must be present for the trait to be expressed. When only one copy of a recessive allele is present, no characteristic is produced. In contrast, a dominant trait requires only one of the two alleles to be present in order for the trait to be expressed.
