About the Mendelian Inheritance Virtual Lab Simulation

In the Mendelian Inheritance simulation you will learn the basic principles of Mendelian inheritance. You will study how Mendel’s postulates can be applied to determine how characteristics are passed from one generation to the next. You will also learn what inheritance looks like at the molecular level. Can you find out if your patient’s children will inherit his color blindness?

Cross purebred mice and observe their phenotypes

To understand the basic laws of inheritance, you will perform mouse experiments and observe how a mouse’s genes can influence its fur color. Can you figure out which fur color is dominant?

Predict the genotypes in the patient’s family

Instead of performing experiments, you will discover how Punnett squares and pedigree trees can be used to predict the genetic makeup of a family. What is true for the fur color in mice, can also be applied to human color blindness!

Experience inheritance at the cellular level

Dive deeper into the laws of inheritance as you watch how cells divide to become gametes inside the reproductive system. By unraveling the laws of X-linked inheritance discover why color blindness affects more men than women.

Learning Objectives

At the end of this simulation, you will be able to…

  • Explain how traits are passed on from parents to their offspring and what causes variation between siblings
  • Describe Mendel’s Laws of Inheritance in color deficiency
  • Compare and predict the phenotypes of offspring with given genotypes using Punnett squares
  • Analyze dominant and recessive alleles, and how they play a part in an individual’s biological make-up
