University of Phoenix Material

Cell Division, Chromosomes, and Inheritance Worksheet

Complete all four sections of this worksheet.

Section I: Mitosis and Meiosis

Part 1: Review the following images on mitosis and meiosis.

Part 2: Explain the events you observe in the pictures.

Part 3: Identify similarities and differences between the pictures you described. Use drawing tools to indicate similarities and differences, where possible.

Section II: Genetic Diversity

Briefly describe the following events and explain their role in creating genetic diversity:

1. Proteins:

2. Crossing over:

3. Independent assortment:

4. Mutation:

Section III: Mendelian Genetics

Post your answers to the following questions from the Problems and Discussion Questions section at the end of Ch. 3 of Concepts of Genetics:

Question 7: 7. Mendel crossed peas having round seeds and yellow cotyledons (seed leaves) with peas having wrinkled seeds and green cotyledons. All the F1 plants had round seeds with yellow cotyledons. Diagram this cross through the F2 generation, using both the Punnett square and forked-line, or branch diagram, methods.

Question 16: Mendel crossed peas having round green seeds with peas having wrinkled yellow seeds. All F1 plants had seeds that were round and yellow. Predict the results of testcrossing these F1 plants.

Seed shape Seed color

W = round G = yellow

w = wrinkled g =green

P1= WWgg x wwGG

Section IV: Chromosomes

Write 1 to 2 paragraphs explaining the role chromosomes play in heredity. Include the structure and function of chromosomes.
