STUDY GUIDE: CH. 13 MEIOSIS AND SEXUAL LIFE CYCLE AN INTRODUCTION TO HEREDITY 1. Explain why organisms reproduce only their own kind and why offspring more closely resemble their parents than unrelated individuals of the same species. -We pass coded information in the form of DNA to our offspring -DNA can change in increments -Within species there may be significant variation -The more distantly related, the more different 2. Explain what makes heredity possible. -DNA is copied and then passed -Inheritance is an orderly, quantitative process -Most often, matched sets of genes are inherited from two parents 3. Distinguish asexual and sexual reproduction. -Asexual- one parent, offspring=clone, DNA passed was grouped by mitosis, faster, simpler, less energy,

Chapter 13 Meiosis and Sexual Life Cycles Overview: Hereditary Similarity and Variation Living organisms are distinguished by their ability to reproduce their own kind Heredity is the transmission of traits from one generation to the next Variation shows that offspring differ in appearance from parents and siblings Genetics is the scientific study of heredity and variation Concept 13.1: Offspring acquire genes from parents by inheriting chromosomes In a literal sense, children do not inherit particular physical traits from their parents It is genes that are actually inherited Inheritance of Genes Genes are the units of heredity Genes are segments of DNA Each gene has a specific locus on a certain chromosome One set of chromosomes is inherited from each parent

How do cells divide? There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by a number of genes. When mitosis is not regulated correctly, health problems such as cancer can result.

Interphase takes the longest to complete. This is because the cell is recovering from cell division in this stage. Cytokinesis is most significantly different between plant and animal cells. They are different because unlike plant cells, in animal cells, a cleavage furrow is formed. The purpose of mitosis is to increase the number of cells that have the same set of DNA ans parent cells. When they split they produce identical cells with a complete set of DNA. Conclusion:
