Genetics Introduction
Genetics • The field of biology devoted to understanding how characteristics are transmitted from parents to offspring • Father of genetics = Gregor Mendel
Gregor Mendel • Austrian monk lived in a monastery • In garden he noticed that some plants were tall, some were short, etc. - Wanted to find out how 2 tall plants could produce a short plant and vice versa. • So he began experimenting!
Mendel’s Experiments • Although Mendel performed many experiments, he is most known for his experiments on heredity of garden pea plants (Pisum satvum)
Heredity • The transmission of characteristics from parents to offspring • Heredity Crash Course – https: //www. youtube. com/watch? v=CBezq 1 f. FUE A
Pea Plants Created Some Vocab! • Characteristic- heritable feature, such as flower color – Each characteristic occurred in 2 contrasting traits • Trait- genetically determined variant of a characteristic, such as a yellow flower color
Characteristics and Traits in Pea Plants Mendel Observed: Characteristic Trait 1 Trait 2 Plant Height Flower Color Tall Purple Short White Pod Color Seed Texture Seed Color Green Round Yellow Wrinkled Green
Characteristics (and each trait) of Pea Plants
Why Pea Plants Worked So Well • Had many traits with only 2 options to study • Reproduces at a rapid rate • Easy to grow!
