Student Instructions

For each assignment, you will complete the following steps:

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?

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.

This assignment will also be assessed using additional criteria provided here.

Assignment: SCIE207 Phase 3 Lab Report

Title: Lab to Determine the Outcome of Heredity

Instructions: You will fill out the Punnett squares and answer a set of questions for each exercise.

When your lab report is complete, submit this document to your instructor in your assignment box.

Using what you learned on the lab animation (and the images below), you will fill in the followingPunnett squares and answer the questions that follow:

Exercise 1: Color Blindness

C

(Type the correct genotypes in the boxes.)

____________

______

______

Exercise 2: Freckles

(Type in the genotypes.)

____________

______

______

Exercise 3: Blood Type

A male has Type A blood, and a female has Type B blood. Could they have a child with Type O blood? Demonstrate how this is genetically possible by filling out the Punnett square.

Choose the correct parental gametes from all of the potential blood type gametes below, and align these in the correct positions around the Punnett square. (Type in the correct gametes. The pink are female gametes, and the blue are male gametes.)

(Type the correct genotypes into the boxes from the possible genotypes shown below).
