What to Focus On

  • Heredity = transmission of characters from parents to offspring
  • Variations = differences among individuals of the same species
  • Acquired variations are NOT inherited; heritable variations ARE inherited

  • Chromosomes are the vehicles of heredity, carrying genes
  • Structure: sister chromatids joined at centromere; telomeres at tips
  • DNA coils around 8 histones → nucleosome → solenoid → supersolenoid → chromosome

  • Watson and Crick proposed the double helix model of DNA in 1953 (Nobel Prize)
  • DNA nucleotide = Nitrogenous Base + Deoxyribose Sugar + Phosphoric Acid
  • Purines: Adenine (A) and Guanine (G) — double-ringed

Common Mistakes to Avoid

The mother determines the sex of the child

Recessive traits always skip a generation and never appear in parents

Dominant traits are more common in a population than recessive traits

Memory Tips
