1. Mendelian Genetics

Key Concepts & Definitions

  • Gregor Mendel (1865): The "father" of genetics, who conducted experiments breeding pea plants to understand how traits are inherited and discovered fundamental genetic principles.
  • Mendelian inheritance patterns: The basic principles of how traits are passed from parents to offspring, including concepts of dominant and recessive alleles, and the segregation and independent assortment of genes.
  • Dominant and recessive allele expression in Mendelian traits: In Mendelian inheritance, the dominant allele is expressed in the phenotype if present, while the recessive allele is only expressed when paired with another recessive allele, as established by Mendel's experiments.
  • P generation: The original parent organisms in a genetic cross, serving as the starting point for breeding experiments.
  • F1 generation: The first filial generation, consisting of the offspring resulting from a cross between P generation individuals. Mendel observed that F1 offspring typically express the dominant trait.
  • F2 generation: The second filial generation, produced by crossing F1 individuals, where Mendel noted the reappearance of recessive traits in a predictable ratio,…
