• Epigenetics: Chemical tags, studied in 2025, regulate gene expression, linking lifestyle to health outcomes.

Inheritance

• Mendelian Genetics: Gregor Mendel’s 1860s pea plant experiments revealed dominant and recessive traits, still foundational in 2024.
• Polygenic Traits: Complex traits, like height, involve multiple genes, mapped in 2025 using AI-driven genomics.

Genomics: Decoding the Genome

Genomics, the study of entire genomes, has revolutionized biology.

Sequencing Advances

• Cost Reduction: By July 2025, sequencing a human genome costs $80, down from $100 million in 2003.
