Mendel’s Work
Father of Genetics
 Gregor
Mendel
 Monk
who enjoyed
gardening
 Studied
plants
the traits of pea
Traits
 Traits
are determined by
genes
 Genes
are passed from
parents to offspring
Traits
 Traits
that are most often seen are
considered to be dominant
 Traits
that seem to disappear and
then reappear in later generations
are called recessive
Pea plant studies
 Curious
about what would
occur if plants with opposite
traits created offspring
Parental generation (P)
 Cross
pollinated two
purebred plants
First generation
 Expected
to create medium sized
plants, but all of the offspring were
tall
 Took
two of these plants &
crossed them
Second generation
¾
of offspring were tall while
¼ were short
