How do you make a cell with half the DNA? Meiosis. This allows cells to have half the number of chromosomes, so two of these cells can come back together to form a new organism with the complete number of chromosomes. This process not only helps produce gametes, it also ensures genetic variation. This section describes the phases of meiosis.
This video helps you understand gametes, zygotes, and haploid/diploid numbers.
The phases of meiosis, Meiosis I and Meiosis II, are explored in details.
Lesson plan is web based. It contains an outline, vocabulary, diagrams, checking for understanding, guided practice, independent practice, and evaluation. Resources for the lesson are available as web links towards the end.

To define and analyze the processes of a concept and build a step-by-step process using a Flow Chart.
Learn about some of the problems which occur when meiosis doesn't go as planned.
Find out why ferns have more chromosomes than humans due to duplications in their genome over the course of evolution.
This study guide compares asexual and sexual reproduction and also looks at meiosis, genetic variation, and life cycles.
