Hope I helped! :)

This type of study method is referred to as:__________Genomics
Explanation:
Genomics involves the mapping of all genes of an organism – this is called the genome.In addition, genomics is the study of the structure of this genome, how it functions/interactions and evolves over time. The <em>-omics</em> suffix is used to signify ‘ in totality’. This study involves the use of equipment like the high throughput DNA sequencers that sequence DNA. Genomic can be used to diagnose and study genetic diseases like cystic fibrosis & Huntington’s disease.
