Abstract

How plant breeders create families with new combinations of traits and make predictions about the inheritance of traits. Discusses Mendel and Punnett.

Objectives

[Fig. 1. A field of wheat stretches to the horizon while neighboring weeds produce offspring for future invasions.]

After reading this lesson you should be able to:

  1. Describe how plant breeders can create families with new combinations of traits and make predictions about the inheritance of traits. [Covered in the sections Super Power through Segregation and Monogenic Characters.]
  2. Outline the experimental approach Mendel used to propose the idea that genes exist, control traits, and are inherited in predictable ways. [Mendel’s Peas]
  3. Compare the methods used by Mendel and Punnett to predict trait inheritance [Punnett and His Square].
  4. Justify the application of gene segregation principles to select plants that will create the future varieties for farmers to grow [Back to the Wheat Breeding Field].
