WILLED THE FAMILY FARM TO HIS BROTHER IN LAW.
•MENDEL BECAME A TEACHER FOR A SHORT WHILE
UNTIL THE STRESS OF THE JOB CAUSED HIM TO
BECOME A PRIEST
•STUDIED MATH AND SCIENCE AT THE UNIVERSITY
OF VIENNA.
•WHEN HE ENTERED THE MONASTARY, HE BECAME A
GARDNER WHICH ALLOWED HIM TO STUDIED PLANT
HEREDITY.
Objective: Draw out Mendel’s
pea plant experiment and
interpret the results.

GENETICS: THE STUDY OF HEREDITY.
MENDEL CROSS POLLINATED HIS PLANTS. HE
DID THIS BY USING A SMALL BRUSH TO
TRANSPORT POLLEN FROM ONE FLOWER TO
THE STIGMA OF ANOTHER FLOWER.
MENDEL STUDIED THE PEA PLANT
BECAUSE:
1) PEA PLANTS REPRODUCE SEXUALLY
AND CAN BE CONTROLLED.
2) PEA PLANTS HAVE MANY OBSERVABLE
TRAITS (HEIGHT, FLOWER COLOR, PEA
COLOR AND SHAPE).
1st Experiment or
Cross
Grandparents
(P generation)
2nd Experiment:
Crossed offspring
from the first
cross to perform
a second cross.
Kids (F1
generation)
WHAT COULD MENDEL DETERMINE FROM
THE RESULTS FROM THE 1ST
EXPERIMENT?
SOME TRAITS ARE DOMINANT (TALL PEA
PLANTS), MEANING THAT THEY ARE
EXPRESSED OVER RECESSIVE (SHORT PEA
PLANTS) TRAITS.
