Answer Details

The white trait is said to exhibit recessiveness. When a yellow maize (which has the dominant yellow trait) is crossed with a white maize (which has the recessive white trait), the resulting first filial generation will only show the dominant yellow trait because it masks the expression of the recessive white trait. However, the recessive trait is still present in the genetic makeup of the plants, and may appear in future generations if certain conditions are met. This is because the recessive trait only shows when two copies of the recessive gene are present in the genotype.
