Here's why:

* Hybrid organism: This means an organism that has two different versions of a gene (alleles) for a specific trait, one from each parent.

* Dominant trait: The allele that determines the trait expressed in the hybrid organism is the dominant allele. It masks the effect of the other (recessive) allele.

Example:

* Consider a flower with a gene for color. Let's say the dominant allele (R) codes for red flowers, and the recessive allele (r) codes for white flowers.

* A hybrid organism with the genotype Rr will have red flowers because the dominant R allele masks the effect of the recessive r allele.
