biology unit 3

Student Instructions

For each assignment, you will use the M.U.S.E. link to complete the lab.

In this lab, you will view evidence and analyze results to answer the following questions:  

• State which genes are dominant (the gene being expressed over another gene(s)) and which genes are recessive (the gene not being expressed when the dominant gene is present).
• How do you know which gene is dominate and which is recessive?
• Report the ratio most likely to be observed across all traits.

Using the M.U.S.E. link, review the background information and animation to complete your report. Use the Lab 3 worksheet for assignment instructions and data collection.

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 incorporate these 2 pieces of the puzzle to interpret the experimental results that were obtained by Gregor Mendel in 1865.
