why is genetics called the physical branch of biology ?
Answers
Answer:
The molecular basis for genes is deoxyribonucleic acid (DNA). ... This structure of DNA is the physical basis for inheritance: DNA replication duplicates the genetic information by splitting the strands and using each strand as a template for synthesis of a new partner strand.
Answer:
Genetics usually discusses the theoretical parts of biology which is the main characteristic feature of the physical branch of biology. That's why genetics is called the physical branch of biology.
Explanation:
Genetics is the study of genes, inheritable variation, and heredity in organisms. It's an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of separate "units of inheritance". This term, still used today, is a kind description of what is reffered to as a gene.
The genes are the introductory unit of passing characters to the next generation. The variation that occurs in one’s body which can be genetically transferred helps in the better adaption of the organism. They can also be disadvantageous for organisms, as there are some diseases which get transferred from one generation to the other and can not be controlled by external agents.
