Genomics

Explanation:

• Genetics is a branch of biology concerned with studying genes, genetic variation, and heredity in living organisms.
• Even though heredity had been observed for millennia, Gregor Mendel, a Moravian scientist and Augustinian priest working in Brno in the 19th century, was the first to examine genetics scientifically.
• Mendel studied "trait inheritance," or the transmission of traits from parents to children across time.
• He observed that organisms (pea plants) acquire traits in "inheritance units" that are distinct from one another.
• This term, which is still used today, is a nebulous description of what is recognised as a gene.
