• Father of Genetics • An Austrian monk at the distinguished monastery of St. Thomas in the Czech Republic • Methodical investigation on heredity – Garden Peas • Carried out his famous experiments on crosses of garden peas (Pisum sativum) from 1856 to 1863. • Discovered “GENES” which determine the traits that an individual inherits.

MENDEL AND HIS GARDEN PEAS:
Mendel chose this plant species for several reasons:
_____ garden peas easily grow, and they produce a large number of offspring.

• First

• Second

• Third

_____, garden peas are bisexual plants; their male and female reproductive structures are located in the same flower, and they self-fertilize.

Mendel conducted his experiments in the following manner:
Production of the pure breeding strains of pea plants. He allowed several populations of garden pea plants to self-pollinate for many generations until he was able to gather seeds that produced only one particular trait-garden peas that produce only whitecolored petals and garden peas that produce only purple-colored petals.

• parental generation

• second parental generation

Mendel conducted his experiments in the following manner:
The crossing of two different varieties of pure breeding strains. He took pollens from a purple-colored flower and transferred them into the stigma of a white-colored flower.

• second parental generation

Mendel conducted his experiments in the following manner:
He called these two varieties of garden peas the P1, or first _____. When the garden peas produced seeds, he gathered and planted them separately. Mendel found out that all the garden peas produced purple- colored flowers. He labeled the first set of offspring as F1, or the first filial generation. The second phase of Mendel's work can be summarized as:
P1 Purple-colored flower x white colored flower
F1 All purple-colored flower

The crossing of the F, generations. Finally, Mendel pollinated the F1, generation.
