GREGOR MENDEL: THE FATHER OF GENETICS
•At 21 years old he joined the Monastery in Brunn, Austria
•His job was to tend to the _________________________
•In _____________________, he entered the University of Vienna
s:
to study
_________________________
•In Math he learned the subject of _________________________
•Statistics helped with his discovery of ________________
•The transmission of characteristics from:
__________________ TO _________________________.
•Mendel later returned to the Monastery and taught high school and
kept his garden
going.
•He studied many types of plants but he is most famous for….

PISUM SATIVUM, AKA: _________________________
Observation of 7 Characteristics of Peas:
– Each occurred in 2 ______________________________traits)
Using statistics, Mendel analyzed the differences he observed.

HIS OBSERVATIONS:
Flower Color :
– Purple Flowers  _________________________ Flower
– Purple Flower  _________________________Flower
Plant Height:
– Tall Plant Seeds --> _________________________ Plants
– Tall Plant Seeds --> _________________________ Plants

Anther: ___________ reproductive part
Stigma: ___________ reproductive part
MENDEL’S METHODS
He _________________________ the experiment by
choosing how the plants were pollinated
Pollination:
- Pollen grains from _______________ transferred to ____________________

Self – Pollination:
- The transfer of pollen from the anther of a flower to the stigma of the same flower, or to different
flowers on the same plant.

Cross-Pollination:
- Involves flowers of 2 _________________________ plants
• The pea plant that Medel studies reproduced by: _______________________
WHAT MENDEL DID
• 1 : Self-pollination can be interrupted
• 2nd: Cross=pollination performed.
• How this is done:
– A) ________________ the __________________ from a flower
– B) _________________________ transfer anther of a flower on one plant to
the stigma of a flower on another plant
●This gave Mendel a _________________________ experiment.

P1 Generation:
_________________________ generation
Mendel used _________________________for each of the 14 traits he
observed
When plants matured, he recorded the number of each type of offspring
produced by each P1 plant
F1 Generation
Generation of _________________________ produced by the P1 plant
First _________________________ generation
These then self-pollinated, and seeds were collected

F2 Generation:
The _________________________ by the F1 generation of plants
Dominant & Recessive
Mendel called the tall height of the plant _______________________
– Because it ___________/______________ or dominated the short
height
The short plant was called _________________________

Tool used to ____________________ the results in genetics
Capital letter “________” represents dominant allele
Lowercase letter “_______” represents recessive
allele
GENOTYPE & PHENOTYPE
● Genotype: The genetic blueprint or what the ________________
(________________) represents: -- “T”
-- “t”
● Phenotype: Is how the allele __________________
“T” = TALL plant
-- “t” = short plant
● Homozygous: An organism with 2____________ alleles for a trait that are EXACTLY the same
( _____________ or TT)
●Heterozygous: An organism that has _________________________ alleles for a trait
( ___________ )
