Lesson 16 Homework 5.4 Answer Key


Welcome to my blog! I know that homework can be tricky, especially when you don’t have the right answers. For students who are working on Lesson 16 Homework 5.4, I’m here to help! In this guide, we’ll go over the answer key to help you understand the concepts covered in your assignments. So, let’s get started!

Understanding Mitosis:

Question 1: Drawing the Stages of Mitosis

Mitosis is the process by which a single cell divides into two identical daughter cells. The stages of mitosis are prophase, metaphase, anaphase, and telophase. Here’s a breakdown of each stage:

  • Prophase: DNA condenses into chromosomes, and the nuclear membrane breaks down.
  • Metaphase: Chromosomes line up in the center of the cell, and spindle fibers attach to the centromeres.
  • Anaphase: Spindle fibers pull sister chromatids apart, moving them to opposite sides of the cell.
  • Telophase: Chromosomes uncoil, and the nucleus reforms around each set of chromosomes.

Exploring Meiosis:

Question 2: Drawing the Stages of Meiosis

Meiosis, which occurs in sex cells, involves stages like early prophase I, late prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, and telophase II. Let’s examine these stages:

  • Prophase I: Homologous chromosomes pair up, and crossing over occurs.
  • Metaphase I: Pairs of homologous chromosomes align at the center of the cell.
  • Anaphase I: Homologous chromosomes separate while sister chromatids remain together.
  • Telophase I: Cell division creates two unique daughter cells with distinct chromosome sets.

Comparing Mitosis and Meiosis:

Question 3: Differences Between Mitosis and Meiosis

Mitosis and meiosis have key distinctions:

  • Mitosis: Produces two identical diploid daughter cells with a full set of chromosomes. No pairing of homologous chromosomes or crossing over occurs. It involves only one division.
  • Meiosis: Yields four non-identical haploid daughter cells with half the number of chromosomes. Homologous chromosomes pair up and undergo crossing over. Two divisions take place.

Defining Genetics:

Question 4: Understanding Genetics

Genetics is the study of genes, heredity, and variation in living organisms. Coined by William Bateson in 1905, genetics explains why offspring inherit traits from parents. Gregor Mendel’s experiments on pea plants laid the foundation for understanding how traits are passed down through generations.


I hope this guide has helped you better understand the Lesson 16 Homework 5.4 answer key and the concepts covered in your assignments. Remember, it’s always important to ask questions and seek help when needed. Keep up the great work, and I wish you all the best in your academic endeavors!
