Observe the 2 females above. Who do you think they are? What is their connection? Well you may be surprised to know that not only are they sisters, but they are also twins! How can twins or even members of the same family be so different? As you explore this chapter you will learn more about how this happens.
It all began with some peas. That’s right. Gregor Johann Mendel was a scientist and an Augustinian friar. He was born in a German-speaking family in what is now known as the Czech Republic. Though farmers had known for thousands of years that crossbreeding of animals and plants could favor certain desirable traits, Mendel’s pea plant experiments, conducted between 1856 and 1863, established many of the rules of heredity, now referred to as Mendel’s laws of inheritance.
Mendel worked with seven characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color. In one experiment, Mendel showed that when a true-breeding yellow pea and a true-breeding green pea were cross-bred their offspring always produced yellow seeds.
