Genetics is the science of heredity and variation. Is this statement true or false?

The statement that genetics is the science of heredity and variation is indeed true. Genetics focuses on how traits and characteristics are passed from one generation to the next through genes, which are segments of DNA. It also studies how these traits can vary among individuals within a population due to genetic mutations, environmental factors, and interactions between genes. This dual focus on both heredity (the transmission of genetic information from parents to offspring) and variation (the differences in traits among individuals) is fundamental to the understanding of biology and evolution, making the statement an accurate definition of the field of genetics.

This definition encompasses not only the basic principles of inheritance but also the complexities of genetic diversity that contribute to the adaptability and evolution of species. This understanding is crucial in various applications, such as breeding programs, medical genetics, and conservation efforts.
