This double bubble map shows the dominant genes and the recessive genes, and their relationships or intersections. In the gene biology field, each parent contributes one gene, one is the dominant gene, another is recessive genes. As for the revessive genes, they have little or no observable
effect on a trait, and only when both genes in a pair are recessive will the recessive form of the trait be visible. In contrast, dominant genes control the appearance of a trait. Try to learn more about genes, and check this double bubble map.
