How does inheritance from the previous generation contribute to the establishment of a common basic body design in the next generation?

Inheritance from the previous generation contributes to the establishment of a common basic body design in the next generation through the transmission of genetic information. Genes, inherited from both parents during sexual reproduction, carry instructions for the development of various traits. The conservation of certain genetic traits over generations results in a common basic body design within a species. While variations arise through genetic recombination and mutations, the foundational genetic blueprint passed down through inheritance ensures the persistence of key features and functions. This commonality in genetic information forms the basis for the fundamental body plan shared within a species across successive generations.
