FOCUS QUESTION

How does meiosis create genetic variation?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Meiosis begins with Meiosis I.
  • Meiosis I followed by Meiosis II.
  • Meiosis I includes Crossing Over.
  • Crossing Over produces Genetic Variation.
  • Meiosis I separates Homologous Chromosomes.
  • Meiosis II produces Four Gametes.
  • Four Gametes are Haploid Cells.

How to read this map

Follow the two divisions and note where crossing over and separation create variation, ending in four gametes.

Learning objectives

  • Distinguish meiosis I from meiosis II.
  • Explain crossing over.
  • Describe how gametes become haploid.
  • Relate meiosis to genetic variation.
