3 Reproduction and Inheritance

This topic area explains how organisms reproduce, how genetic information is carried and how inherited patterns are represented. It bridges cell division ideas from earlier work to variation and heredity.

Core Role

  • Distinguish sexual and asexual reproduction clearly.
  • Connect DNA, genes, chromosomes and gametes into one inheritance model.
  • Introduce the genetic vocabulary needed for later selective-breeding and genetic-modification work.

Topic Pages

  • 3a Reproduction: Reproduction combines the production of new individuals with the early stages of development. The topic brings together plant reproduction, human reproduction, germination and the contrast between sexual and asexual methods. 3 learning objectives.
  • 3b Inheritance: Inheritance explains how information stored in DNA influences phenotype and how that information passes between generations. The topic links molecular ideas to genetic crosses, cell division, variation, mutation and natural selection. 4 learning objectives.
