Inheritance and Variation of Traits
Mitosis

Mitosis

Students build their own Mitosis movie! As they stages are put in the correct order, a real video of that stage appears with a description as friendly reminders about the core of organism growth and development.
Dog Breeding Game

Dog Breeding Game

The goal of this educational game is for students to breed a certain type of border collie puppy by selecting parents with the right traits. Students will be trying to match certain coat colors, coat lengths, and ear types.
Bacterial Identification Virtual Lab

Bacterial Identification Virtual Lab

This virtual lab will familiarize students with the science and techniques used to identify different types of bacteria based on their DNA sequences. Students will see the connection among various molecular biology and bioinformatics topics rather than considering them in isolation.
 DNA Extraction Virtual Lab

DNA Extraction Virtual Lab

The Genetic Science Learning Center is an amazing web site. It is filled with conceptually clear and timely information and explanations. Their mission is to “help people understand how genetics affects their lives and society”. This incredible resource is from the University of Utah. Try to isolate DNA from a cheek cell in a virtual laboratory simulation! Flash is required.
DNA makes DNA

DNA makes DNA

John Kyrk has produced some of the most incredible animations for biology and biochemistry. They are truly groundbreaking in the way they display information abot the most important molecules and processes of life. The “learning tool” John has created is called Cell Biology Animation, just click to visit this wondrous work. Flash is required.
Mendelian Inheritance Lab

Mendelian Inheritance Lab

An evolution and genetic diversity virtual laboratory experiment that walks students through topics like making a pedigree, applications of the Mendelian laws, gene pairs, inheritance, and more! This site also has virtual labs for DNA Extraction, Exploring Mutant Organisms, and Bacterial Transformation.
DNA from the Beginning

DNA from the Beginning

DNA From the Beginning is a learning tool that covers all aspects of genetics from classical genetics through molecules of genetics to genetic organization and control. Each of the 41 subtopics is supported by text, animations, pictures, audio/video, a bio of a famous scientist in that field, a problem/quiz, and additional links. This is essentially a genetics course online! This tool comes to us from the Dolan DNA Learning Center at Cold Spring Harbor Lab. Works on all devices!
LabBench: Genetics of Organisms

LabBench: Genetics of Organisms

In this laboratory students will study the patterns by which physical characteristics are transmitted from generation to generation and use statistical analysis to support their conclusions. Students breed fruit flies to determine whether a trait follows a monohybrid or dihybrid pattern of inheritance and whether it is sex-linked or autosomal.
VIDEO: Introduction to Molecular Genealogy

VIDEO: Introduction to Molecular Genealogy

This is a great video made by the Genetic Science Learning Center in Univeristy of Utah. DNA analysis can help build the family tree. Find out about autosomal, X chromosome, Y chromosome, and mitochondrial DNA. Works on all devices.
Virtual Lab: Do Some Genes Maintain More Than One Common Allele in a Population?

Virtual Lab: Do Some Genes Maintain More Than One Common Allele in a Population?

Do Some Genes Maintain More Than One Common Allele in a Population? Students explore this question as they work through an advanced virtual laboratory experiment creating hypotheses, collecting and analyzing data, and drawing their own conclusions.

KEY CONCEPTS

Inheritance of Traits (LS3.A)

  • Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species’ characteristics are carried in DNA. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Not all DNA codes for a protein; some segments of DNA are involved in regulatory or structural functions, and some have no as-yet known function. (HS-LS3-1)

Variation of Traits (LS3.B)

  • In sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations, which are also a source of genetic variation. Environmental factors can also cause mutations in genes, and viable mutations are inherited. (HS-LS3-2)
  • Environmental factors also affect expression of traits, and hence affect the probability of occurrences of traits in a population. Thus the variation and distribution of traits observed depends on both genetic and environmental factors. (HS-LS3-2),(HS-LS3-3)
