Practice and Revision - Heredity and Evolution
Let us practise and revise what we learned about heredity and evolution. Heredity, the passing of traits, and evolution, the change in speci
Core concept
Genetic inheritance follows patterns established by Mendel's laws, with dominant and recessive alleles determining observable traits in offspring.
How it works
Evolution occurs through natural selection, where organisms with advantageous traits are more likely to survive and reproduce.
Why it matters
Evidence for evolution includes fossil records, comparative anatomy, and genetic similarities between related species.
Key detail
Understanding heredity and evolution helps explain biodiversity, adaptation, and the interconnectedness of all living organisms.
