This lesson emphasizes the phases of meiosis and how it is different from mitosis. Students will model each phase using candy worms as chromosomes and other types of candy to represent other cellular structures. This gives students a hands on perspective of meiosis, allowing them to better grasp the differences in phases, as well as to understand the importance of meiosis in sexual reproduction.

Type: Lesson Plan

Students will model stages of mitosis and meiosis using yarn. By the end of the lesson, the students will be able to recognize the difference between mitosis and meiosis, know what type of cells are produced from mitosis and meiosis, and how many new cells are created at the end of each process.

This lesson is designed for student with mild/moderate disabilities enrolled in an Access class or in the inclusion classroom with assistance from the support facilitation teacher or possibly an Advanced Placement Biology student.

Type: Lesson Plan

This lesson requires the students to simulate the movement of chromosomes during mitosis and meiosis using different-colored pipe cleaners. The pipe cleaners allow the instructor to highlight both recombination (crossing over) and independent assortment, two important components of meiotic cell division. The processes that create variation among gametes are also emphasized.

This lesson plan includes excellent teacher support in the form of videos that explain how the pipe cleaners should be manipulated to demonstrate the concepts of mitosis, meiosis, and independent assortment.

Learn how to describe Meiosis, the process by which sex cells--the sperm and the egg--are created in living things. In this interactive tutorial, you will also discover how sexual reproduction results in genetically diverse offspring.

Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis. This tutorial will help the learners to understand the process of spermatogenesis.

Type: Tutorial

This tutorial discusses the process of meiosis which results in the formation of sperm cells and egg cells. It is the process by which diploid cells become haploid gametes.

Type: Tutorial

This animation describes what occurs in a cell during the process of meiosis. Each phase of meiosis is defined and a visual accompanies the definition. Students can see the process of a diploid cell becoming a haploid cell.

Type: Tutorial

This tutorial will help you to understand the three unique features of meiosis and how meiosis is related to genetic inheritance.

Type: Tutorial

This animation details the process of meiosis and explains each of the stages.

Type: Tutorial

This tutorial will help you to understand how meiosis II is very similar to mitosis. In both cases, chromosomes line up and sister chromatids are separated by the action of the spindle fibers.

Type: Tutorial

This tutorial will help you to understand the unique features of the first round of meiosis. In meiosis 1, members of homologous chromosome pairs are separated. This results in the segregation of genes into two gametes.

Type: Tutorial

An important fundamental concept of genetics is the idea of independent assortment. This states that genes are inherited independently of one another. This tutorial will help you better understand crossing over and independent assortment during meiosis.

Type: Tutorial

Meiosis is the process by which a diploid eukaryotic cell divides to generate four haploid cells. This process is important in forming gametes for sexual reproduction. This tutorial will help you understand the process of meiosis and its various stages.

Type: Tutorial

This tutorial will help you to understand the basic principles of genetic inheritance which are segregation and independent assortment of two alleles.

The principles of genetic inheritance are based on unique features of meiosis. Synapsis of homologous chromosomes and the separation of the homologous pairs during anaphase 1 cause the segregation of alleles. Crossing over and the random separation of chromosomes cause independent assortment.

Type: Tutorial

This tutorial will help students understand the process of meiosis. Each stage in the process of meiosis is explained and animated in this tutorial.

This virtual lab has three components: a short tutorial describing meiosis, a series of microscope slides allowing students to identify stages of meiosis, and a karyotyping activity. The first components support student understanding of mitosis and meiosis, as well as gamete formation. The karyotyping activity is fun and interesting for students, but is not necessary for mastery of NGSS science benchmarks.

Type: Virtual Manipulative

This is a lab/activity that uses dragons as "research subjects" for genetics research. It highlights independent assortment as well as gene linkage. Students will do the first part of the activity using independent assortment (genes on different chromosomes). The second part of the activity looks at genes on the same chromosome, and how linkage plays a part in allele assortment. It can be used to show how crossing over allows increased variation when involving linked genes.

Worksheets are available in both Word and PDF formats, for both teacher and student. There is an additional dragon genetics lab that illustrates the principles of Mendelian genetics as a whole.
