GED® Science: Genetics & Heredity (Deep Dive)
A deep dive into how traits are passed from parents to offspring, expanding the single 'Genetics & Heredity' lesson from the GED® Life Science course into a full mini-course. You'll explore DNA and its base-pairing code, how genes and chromosomes carry instructions to build proteins, the difference between genotype and phenotype, how to use Punnett squares to predict offspring, how meiosis creates variation, and how mutations and pedigrees reveal inheritance patterns. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.

Why do you resemble your parents? The answer is DNA — the molecule that stores the inherited instructions for building and running a living thing. …
