** Mendel **
Mendel was an Austrian monk who taught natural science and worked on plant
He developed a basic understanding of genetics and inheritance.
** Mendels Work **
It took him 2 years to select the pea plant as his subject.
He collected data for 10 years.
His sample sizes were large; he tabulated results from 28,000 pea plants.
He replicated his experiments.
He analyzed his data with statistics (probability theory).
** Characteristics of Garden Peas: **
Peas are easy to grow, and take little space.
They are inexpensive.
They have a short generation time compared to large animals so that a large
number of offspring can be obtained in a short amount of time.
They have some distinct characteristics that are easy to recognize. These
characteristics can be used when trying to determine patterns of
They are easily self-fertilized or cross fertilized.
** Traits Studied by Mendel **
smooth or wrinkled seeds
yellow or green seeds
red or white flowers
inflated or constricted pods
green or yellow pods
axial or terminal flowers
tall or dwarf plants
** Mendels Crosses **
Mendel used pure-breeding individuals in the first (P) generation.
* yellow X green
* all yellow
* 3/4 yellow, 1/4 green_*
** Mendels Results for 7 different crosses **
smooth X wrinkled seeds all smooth
1850 wrinkled 2.96:1
yellow X green seeds all yellow
2001 green 3.01:1
axial X terminal flowers all axial
207 terminal 3.14:1
