Final answer:
DNA fidelity guarantees accurate inheritance while DNA acts as the raw material for inheritance. Genetic recombination during meiosis rearranges variant genes.
Step-by-step explanation:
The fidelity with which DNA is inherited guarantees the accurate transmission of genetic information from one generation to the next. This ensures that offspring inherit the correct set of genes from their parents, leading to the preservation of traits and characteristics.
DNA serves as the raw material on which inheritance works. It contains the instructions for the development and functioning of organisms, providing the blueprint for traits and determining the phenotype or observable characteristics of an organism.
Genetic recombination during meiosis rearranges variant genes, contributing to genetic diversity within a species. This process involves the exchange of genetic material between homologous chromosomes, resulting in new combinations of alleles and the generation of unique genotypes and phenotypes.
