Lesson: Meiosis

How is the process of sexual reproduction similar to and different from mitosis/asexual reproduction?

This lesson continues the concept of division, but from the perspective of sexual reproduction. In order to reproduce in this manner the genetic components of cells must be reduced in half (from diploid to haploid) so that the recombination into a zygote will return the cell to its diploid state. This process is similar to mitosis, but with key differences that allow for genetic variation and, inevitably, evolution.

Lecture Notes: #content

Meiosis - notes - this is a resource which has greater detail and information

Meiosis Presentation - displays the information, diagrams and processes of meiosis, including crossing over and gametogenesis

Activities, Assignments, Etc.

Meiosis Research Questions (answers) - students use internet and other resources to answer these questions as introduction to the concepts of Meiosis

Diagrams - Meiosis - (first review "Circle of Life" and go over "research questions", then draw simplified diagram of Meiosis I & II, Crossing over using Meiosis presentation
