Question
Chapter 34, Problem 1.1Q
Summary Introduction
To determine: The difference between accessory reproductive organs and secondary sexual characteristics.
Introduction: The mechanism by which the genes of two individuals are combined to produce offspring is called sex. Gametes are the specific cells that are produced by each parent during sexual reproduction.
Expert Solution & Answer
Explanation of Solution
In sexually reproducing animals, males and females are differentiated on the basis of primary reproductive organs, accessory reproductive organs, and secondary sexual characteristics. Following are the differences between accessory reproductive organs and secondary sexual characteristics:
| No. | Criteria | Accessory reproductive organs | Secondary sexual characteristics |
| 1. | Definition | The accessory organs are the reproductive organs other than gonads that differ in males and females. | The secondary sexual characteristics are properties of nonreproductive tissues and organs that differ in males and females. |
| 2. | Examples | In human males, penis, vas deferens, and the other sperm carrying ducts out of the testes are the accessory reproductive organs. | In human males, facial hair, chest hair, and a deep voice are secondary sexual characteristics. |

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
