Final answer:
Hereditary information is transmitted from nucleus to nucleus during cell division and from parents to offspring through mitosis or meiosis plus fertilization.
Step-by-step explanation:
Hereditary information is passed from nucleus to nucleus. During cell division, DNA is replicated and passed from the parent cell to the daughter cells, ensuring that each new cell contains a complete set of hereditary information. In sexually reproducing organisms, this information is also transmitted from parents to offspring through the processes of mitosis or meiosis followed by fertilization, allowing inherited characteristics to be passed down through generations.
