Key Topics to Revise

1

Variation and Reproduction

  • Reproductive processes create individuals that are similar but subtly different
  • Asexual reproduction produces limited variations due to small DNA copying errors
  • Sexual reproduction maximizes successful variations and creates greater diversity
2

Mendel's Laws of Inheritance

  • Gregor Mendel studied inheritance patterns in pea plants
  • Both parents contribute equal amounts of genetic material to offspring
  • Each trait is controlled by two factors (genes) - one from each parent
3

Genetic Basis of Inheritance

  • DNA contains information for making proteins that control traits
  • Genes are sections of DNA that code for specific proteins
  • Proteins (enzymes, hormones) determine observable characteristics
4

Sex Determination

  • Different species use different methods for sex determination
  • Some species rely on environmental factors (temperature in reptiles)
  • Some organisms can change sex during their lifetime
