Similarly Genetically Different

Mutations are not just deformed creatures we see in movies—they happen every day! Scholars study the different types of genetic mutations in the 11th installment of a series of 17 lessons. A creative activity uses candy and other food...

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...

After teaching about the process of meiosis, use this presentation to inform your biology buffs of problems that can possibly occur. Gene mutation is mentioned as a review, and then different forms of chromosome mutation are explored:...

Potatoes have more chromosomes than humans. A video explores the number of chromosomes various species have and the theories of the differences. It discusses the process of how genes combine as well as the processes of making extra copies.

Proving microscopic structures exist is a difficult task. Learn how scientists did just that in the mid-1800s as they set out to identify the cellular structures related to genetics. The online lesson explains the collection of work that...

Everything is in the genes. Individuals observe 14 different traits of themselves. Using pipe cleaners and beads, the learners create models of a chromosome representing their traits. The class then compares and contrasts everyone's...

Women just have that X factor! High schoolers watch a short video about X chromosome inactivation, which explains how identical twins can differ genetically even though their DNA sequence is the same.

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

Chromosomes contain keys to history including links from royalty to Neanderthals. Young scientists learn about Ivan Wallin's research into chromosomes with an animation and videos. Then, the concept connects to mysteries related to...
