1. Genetic information and inheritance

Key Concepts & Definitions

  • Genetic information : Genetic information is stored in DNA and encodes traits through the alleles it contains.
  • Alleles : Alleles are different versions of a gene that can produce different possible trait outcomes.
  • Diploid genome : A diploid genome means an organism has two copies of each chromosome and therefore two copies of each gene.
  • Meiosis and mitosis : Meiosis and mitosis are cell divisions that transmit genetic information to the next generations.

Essential Points

  • Genetic information is carried by DNA and is passed to offspring through meiosis and mitosis.
  • Humans are diploid: they carry two copies of each chromosome, so each gene has two copies.
  • Different alleles exist, and their combination in individuals is what links inheritance to traits.
  • To learn inheritance laws, you must master genetic vocabulary and how alleles are transmitted using Punnett square grids.
