How does molecular genetics add to our understanding of genes is by simply </span>studying them. <span> Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. </span>This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. <span>And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.<span>

Hybridization is the process of interbreeding between the plants belonging to different species (interspecific hybridization) or genetically distinct individuals of same species (intraspecific hybridization). The offspring produce by this method is called as hybrid. The hybridization allows the breeding between parent plants that have desired characteristics, which results in production of hybrid having desired characteristics of both of the parents.
Therefore, in the given situation hybridization is the process that should be adopted to combine the traits of the two varieties of plants.
I deeply apologize if this is not what you meant.
Explanation:
