Chapter 11.2 Notes - Applying Mendel's Principles

  1. 1. Chapter 11.2 Applying Mendel’s Principles
  2. 2. Vocabulary • Probability – the chance an event will occur • Independent assortment – one of Mendel’s principles that states that genes for different traits can segregate independently during the formation of gametes
  3. 3. Vocabulary • Gene – a factor that is passed from parent to offspring • Allele – one of a number of different forms of a gene
  4. 4. Vocabulary • Segregation – separation of alleles • Gametes – sex cells (egg cells or sperm cells)
  5. 5. Vocabulary • Homozygous – having two identical alleles for a particular gene • Heterozygous – having two different alleles for a particular gene • Phenotype – physical characteristics of an organism – Example – widow’s peak or no widow’s peak • Genotype – genetic makeup of an organism – Example – RR, Rr, rr
  6. 6. Mendel’s Principles • Biological characteristics are inherited through units called genes. –Genes are passed from parents to offspring
  7. 7. Mendel’s Principles • Principle of Dominance – some alleles are dominant and others are recessive – Organism with at least one dominant allele for a form of a trait will show that form of a trait – Organism with a recessive allele will show that form only when the dominant allele is not present
