The Chromosomal Basis of Inheritance — Sex-Linked Traits, Linked Genes, and Genetic Disorders Explained | Chapter 15 of Campbell Biology Welcome to Last Minute Lecture! This post covers the chromosomal basis of inheritance, connecting Mendel’s laws to the behavior of chromosomes as described in Chapter 15 of Campbell Biology . Discover how genes are located on chromosomes, how sex-linked traits and linked genes are inherited, and how chromosomal alterations can result in genetic disorders. Watch the full video summary below and subscribe for clear, chapter-by-chapter genetics insights! Introduction: Chromosomes as the Carriers of Genetic Information The chromosome theory of inheritance links Mendel’s discoveries to chromosome behavior during meiosis, explaining how genes are transmitted from parents to offspring. Chromosomes segregate and assort independently, underlying the patterns of inheritance observed by Mendel. Sex-Linked Inheritance Sex-Linked Genes: Located ...

Mendelian Genetics and Extensions — Laws of Inheritance, Probability, and Genetic Disorders Explained | Chapter 14 of Campbell Biology Welcome to Last Minute Lecture! This post explores Mendelian genetics and its modern extensions, as presented in Chapter 14 of Campbell Biology . Discover how Gregor Mendel’s experiments laid the foundation for understanding how genes are inherited, how probability laws predict genetic outcomes, and how more complex inheritance patterns go beyond simple dominance and recessiveness. Watch the full video summary below and subscribe for clear, chapter-by-chapter genetics lessons! Introduction: Mendel’s Legacy in Genetics Gregor Mendel’s work with pea plants established the laws of segregation and independent assortment—principles that remain at the core of modern genetics. This chapter shows how Mendel’s discoveries explain both simple and complex inheritance in all living things, including humans. Mendel’s Laws of Inheritance Law of Segr...
