Question

The term genetics was coined by
A. Morgan
B. William Bateson
C. Johannsen
D. Carl Correns

Answer 1

Hint: The most basic functional and physical units of heredity are known as genes. The branch of biology that helps in the study and variation of genes is known as genetics. It helps to identify and study the mechanism and inheritance of traits from generation to generations.

Complete answer:
1.Thomas Hunt Morgan was an American biologist who specializes in evolution, genetics and embryology. He was conferred the Nobel prize in 1933 for his research and role of chromosomes in heredity.
2. Wilhelm Johannsen is known as the botanist from Denmark whose work included pharmacy, genetics and physiology of plants. He was the one who has given the word gene in order to describe the Mendelian units of heredity.
3. Erich Correns is known as one of the German botanists and geneticists. He is notable primarily for his work on the principles of heredity.
4. William Bateson is known as one of the English biologists who became the chief populariser of the ideas of Gregor Mendel in the advent of the twentieth century. He is known for the introduction and usage of term genetics to describe the study of heredity. In his coupling and repulsion theory he used his term genetics first in 1905. Hence William Bateson the first person who has given the term genetics in the study of botany.

Hence, the correct answer is option (B).

Note: Deoxyribonucleic acid or DNA is a molecule composed of two polynucleotide chains. These chains loop around each other to form a double helix carrying genetic instructions in order to develop, grow and reproduce all known organisms and some viruses. It is another name for the molecule carrying genetic information.
