Chromosomes and Karyotypes
One in 150 babies born presents a chromosomal condition, and society is getting closer to recognizing these as normal variations. Scholars learn about chromosomes and karyotypes with a resource that focuses on Down Syndrome as well as...

Chromosome Karyotyping
High schoolers explore chromosome karyotyping. In this chromosome karyotyping lesson plan, students use a chromosome kit to explore chromosome syndromes and disorders. They also produce a large model of a cell with chromosome to simulate...

The Human Genotype
Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

Lesson 10: Karyotypes
Students predict traits of future offspring. In this biology lesson, students study karyotyping to predict genetic disorders. They research an assigned karyotype and present information about it.

What is the purpose of Karyotyping?
Students explain how karyotyping is used to diagnose specific genetic disorders. They use karyotypes to make observations and analyze chromosomal errors. This activity can be completed online or without computer access.

Making Karyotypes
In this karyotype worksheet, students answer 5 pre-lab questions before cutting out numbered chromosomes and matching them to unnumbered chromosomes to create a karyotype.

Human Heredity Vocabulary
Ninth graders review the terms "aneuploidy," "fetus," and "karyotype" in this vocabulary worksheet, which includes three multiple choice questions about each term. This activity could be expanded into a more developed vocabulary lesson...

Karyotypes and Inheritance of Chromosomes
Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

Modeling Allele Distribution Through Meiosis and Fertilization
The main objective of this activity is to illustrate the variation that results from crossing-over during prophase I of meiosis. Other sources of variation from generation to generation are: (1) independent assortment (223 possible...

How Can You Predict the Characteristics of an Unborn Baby?
Students compare three sets of unlabeled human chromosomes and gather related data, trace chromosomes to pair them, and make observations about them.

Genetic Disorders
Young scholars examine how living cells create new cells and how genetic mutations can cause disorders and be inherited. In this genetic reproductionn lesson students create their own PowerPoint presentation.
Curated OER
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

The Chromosome Connection
Students evaluate the degree of chromosome similarity and difference between humans and apes. Students infer about the relationship between a human and ape based on similarities found.
