🧬 Quick Study Guide

  • 🌱 Genes: The basic units of heredity, composed of DNA and arranged on chromosomes.
  • 🔬 Alleles: Different forms of a gene. Individuals inherit two alleles for each gene, one from each parent.
  • 💡 Genotype: The genetic makeup of an individual (e.g., AA, Aa, aa).
  • 👁️ Phenotype: The observable characteristics of an individual, resulting from the interaction of its genotype with the environment (e.g., blue eyes, tall height).
  • Dominant Allele: An allele that expresses its phenotype even when paired with a recessive allele.
  • Recessive Allele: An allele that expresses its phenotype only when paired with another recessive allele.
  • 📜 Mendel's Laws:
    • ⚖️ Law of Segregation: Allele pairs separate during gamete formation.
    • 🔗 Law of Independent Assortment: Genes for different traits are sorted separately from one another during gamete formation.
  • 🧬 Punnett Square: A diagram used to predict the genotypes and phenotypes of offspring from a genetic cross.
