Get Focused

 

Has anyone ever told you that you look just like your mother, your father, or your great uncle Jed? While the question of how we got many of our physical traits can be complex to explain, a few are very simple to explain. Traits like hairline, thumb curve, and earlobe attachment are examples of traits that are controlled by one gene with two alleles. Comparing which traits your parents have to those you and your siblings have is a quick way to observe inheritance in action. 

 

In this lesson, you will learn the patterns of inheritance that Mendel discovered by studying pea plants. You will become familiar with techniques and conventions used by geneticists to trace the inheritance of traits from one generation to the next.

 

In this lesson, the following focusing questions will be examined:

  • What are the simple principles of single trait inheritance?
  • How can genotype be determined from phenotype?
Module 6: Lesson 2 Assignment

 

Your teacher-marked Module 6: Lesson 2 Assignment requires you to submit a response to the following:

  • an activity on mouse genetics for assessment

Download a copy of the Module 6: Lesson 2 Assignment to your computer now. You will receive further instructions on how to complete this assignment later in the lesson. Remember to continue to add new terms to your flash cards as you work through the lesson.

 

The other questions in this lesson are not marked by the teacher; however, you should still answer these questions. The “Self-Check” and “Try This” questions are placed in this lesson to help you review important information and build on key concepts that may be applied in future lessons.

 

You should record the answers to all the questions in this lesson and place those answers in your course folder.

 

Remember you also have the option of trying additional questions from the textbook for further practice. Consult with your teacher for the answers to these questions. The Key will also provide you with many Diploma-Exam-style multiple choice, numerical response, and written response questions that will be an excellent review of the module. Practising responding to these types of questions is good preparation for the Diploma Exam.
