The correct answer is A. Genetics.
Genetics is the study of genes and heredity. It is a branch of biology that deals with the transmission of genetic information from parents to offspring. Genetics also studies the variation of inherited traits within a population.
Evolution is the process by which species change over time. It is a gradual process that can take millions of years. Evolution is driven by natural selection, which is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce.
Embryology is the study of the development of an embryo from conception to birth. It is a branch of biology that deals with the formation and development of the embryo. Embryology is a complex field that involves the study of many different aspects of development, including cell division, tissue differentiation, and organogenesis.
Molecular biology is the study of the structure and function of molecules that make up living things. It is a branch of biology that deals with the study of the molecules that are essential for life, such as DNA, RNA, proteins, and carbohydrates. Molecular biology is a rapidly growing field that is essential for understanding the basic processes of life.
In conclusion, the correct answer to the question “It is the study of hereditary characters transmitted from parents to offspring” is A. Genetics.
