Meiosis and Genetics (AP Bio Unit 5) Made Super Simple!

🎯 Struggling with AP Bio? With Learn-Biology.com, you’ll gain the skills and confidence to earn a 4 or 5 on the AP Bio exam — guaranteed! ➡️ https://learn-biology.com/apbiology 🧬 Master AP Bio Unit 5: Heredity — Meiosis & Mendelian Genetics (Updated for 2025) 🧬 Nervous about meiosis, dihybrid crosses, linkage, recombination, or nondisjunction? This complete lesson walks you through everything you need to know for AP Biology Unit 5 (Heredity) — aligned with the 2025 College Board updates. 💡 In this video you’ll learn: ⭐ The big picture of meiosis: haploid vs. diploid, homologous chromosomes, germ cells vs. gametes, and how meiosis differs from mitosis ⭐ How meiosis generates genetic variation: independent assortment and crossing over / recombination, plus how fertilization adds even more diversity ⭐ Sex determination systems: XY in mammals, ZW in birds, temperature-dependent sex in reptiles, and haplodiploidy in bees/ants/wasps ⭐ Nondisjunction & chromosomal variation: trisomy (e.g., Down syndrome), monosomy (e.g., Turner syndrome) ⭐ Core Mendelian genetics: genes/alleles, dominant vs. recessive, genotype vs. phenotype, monohybrid and dihybrid crosses, P/F1/F2 generations ⭐ Independent assortment and the rule of multiplication for multi-gene (tri-hybrid) problems ⭐ Linked genes & recombination: test crosses, parental vs. recombinant phenotypes, and mapping genes with recombination frequency ⭐ Sex-linked inheritance (X-linked traits): hemophilia, red-green color blindness; how carrier moms and affected dads pass traits ⭐ Non-nuclear inheritance: mitochondrial (and chloroplast) genes and maternal inheritance ⭐ Incomplete dominance (red/white → pink) and pleiotropy (new emphasis for 2025) with sickle-cell disease and cystic fibrosis ⭐ Genotype × environment interactions: hydrangea color, Himalayan/siamese coat patterns, and more 📘 Download your FREE AP Bio Checklist — it tells you exactly what to study for Unit 5 (and the rest of AP Biology)! ➡️ https://apbiosuccess.com/checklist 🧬 Chapters 00:00 – Introduction & Overview of Unit 5 (Heredity) 01:09 – Meiosis Basics — Haploid vs Diploid Cells, Homologous Chromosomes 06:01 – How Meiosis Creates Genetic Variation — Independent Assortment & Crossing Over 15:02 – The Stages of Meiosis I and II (Interphase → Cytokinesis II) 18:43 – Sex Determination Systems — XY, ZW, Temperature & Haplodiploidy 26:20 – Nondisjunction and Chromosomal Variation (Trisomy & Monosomy) 30:03 – Mendelian Genetics — Segregation, Dominance, and Monohybrid Crosses 36:38 – Dihybrid Crosses and Independent Assortment in Meiosis 41:50 – Using the Rule of Multiplication to solve Genetics problems (trihybrid crosses) 43:17 – Linked Genes & Recombination — Fruit Fly Evidence and Mapping Genes 53:03 – Sex-Linked Traits — Hemophilia, Color Blindness & X-Linked Inheritance 59:03 – Non-Nuclear Inheritance — Mitochondrial and Chloroplast Genes 1:01:03 — Incomplete Dominance 1:02:36 — Pleiotropy — Sickle Cell and Cystic Fibrosis 1:09:10 – Genotype × Environment Interactions — Hydrangeas & Himalayan Rabbits 1:11:30 – Next Steps for AP Bio Success (Study Plan & Resources) 📱 Crush your course with Mr. W’s Biomania App! iPhone ➡️ https://apbiosuccess.com/biomaniafori...
