Using the Laws of Inheritance

Gregor Mendel’s studies laid the foundation for modern genetics. In a series of elegant experiments, Mendel was able to deduce the most fundamental laws of single-gene and multiple-gene inheritance without having the scientific data on chromosomes, their structure, or meiotic segregation. In this lab, you will learn about and apply examples for 3 different patterns of human inheritance of traits.

In this lab, you will view information and complete activities to answer the following questions about genes and inheritance:

• What is a Punnett Square? How can it be used to analyze possible genetic outcomes for offspring?
• What is dominant/recessive inheritance?
• What is X-linked inheritance?
• What is codominant inheritance of genes?
