Dragon Genetics -Independent Assortment and
Gene Linkage
Description
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.

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

Unique Features of Meiosis
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.
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.
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.
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.
This video discusses the phases of Meiosis (Part 1 of 2).
This video discusses the phases of Meiosis (Part 2 of 2).
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.
This animation details the process of meiosis and explains each
of the stages.
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.
This tutorial will help you to understand the three unique
features of meiosis and how meiosis is related to genetic
inheritance.
This tutorial will help you to understand the basic principles of
genetic inheritance which are segregation and independent
assortment of two alleles.
Unique Features of Meiosis
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.
Lesson Plan

Making Mitosis with Yarn
Description
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.
This lesson requires the students to simulate the movement of
chromosomes during mitosis and meiosis using differentcolored pipe cleaners. The pipe cleaners allow the instructor to
highlight both recombination (crossing over) and independent

Assortment
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.
In this lesson, students demonstrate the law of segregation
during meiosis, which states that a pair of alleles for a particular
trait separates during cell division. They will then use Mendel's

square, to predict the genotype and phenotype of offspring from
a particular cross. They will test these predictions by simulating
the results of particular crosses.

Virtual Manipulative
Name
Description
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.
