Question

Branch of biology dealing with heredity and variation is called
(a)Palaeontology
(b)Evolution
(c)Genetics
(d)Ecology

Answer 1

Hint: They are a branch of the biology involved in the study of heredity, its biological process, the study of genes, genome, cell cycle, heredity, inherited genes, and a lot more. Its concepts had been observed for hundreds of years, however, it had been scientifically studied by Gregor Mendel.

Complete answer:
Genetics is defined because of the branch of biology that deals with the study of genetic variation genes, and heredity. Heredity is the term used for transmission of the traits from one generation to subsequent generations. It’s because of heredity that the offspring look almost like their parents. Any differences present between individuals of any species, caused either by genetic difference or by the effect of environmental factors, is named variation. Variations are often shown in physical appearance, metabolism, behavior, learning and capacity, and other obvious characteristics.

Additional Information: Genetics is the science which deals with the mechanisms liable for similarities and differences among closely related species i.e. it's the study of the transmission of body features: i.e., similarities and differences, from parents to offspring and the laws associated with this transmission. Paleontology is the branch of biology which supplies fossils of animals and plants that lived up to billions of years ago. Evolution is the change within the characteristic of living organisms over a generation. Ecology is the branch of biology which deals with the interaction between non-living and living components within the environment.
So, the correct answer is ‘Genetics’.

Note: Mendel is taken into account as the daddy of Genetics. The term ‘genetic’ was given through William Bateson in 1905. A few years later, scientists had rediscovered his research and built upon it. Modern genetics has enabled a deeper understanding of the varied forces at play. Traits and characteristics, how they travel from parents to offspring, were well understood. Eventually, disorders that were caused because of genes (faulty genes) were discovered. This causes the event of viable treatments to deal with these disorders.
