Gregor Johann Mendel
was a monk and tended monastery gardens. grew many varieties of peas and noticed 7 different characteristics in a species of pea plant
7 characteristics
flower position, flower color, plant height, seed color, seed texture, pod color, pod appearance
flower position (2 different traits)
axial (long stem) and terminal (end)
flower color (2 different traits)
purple and white
plant height (2 different traits)
tall and short
seed color (2 different traits)
green and yellow
seed texture (2 different traits)
round and wrinkled
pod color (2 different traits)
green and yellow
pod appearance (2 different traits)
inflated and constricted
phenotype
physical outcome looks like
genotype
actual genes from both parents (PP, Pp, pp)
mendels experiment
noticed that purple color was dominant 3:1
stigma
tip/top of ovary (female part)
style
(~stem/tube) of ovary (female part)
ovary
female part of flower
ovule
inside ovary (female part)
filament
(~stem) that connects to pollen (male part)
anther
(~ball) holding pollen (male part)
pollen
“sperm” of plant (male part)
when pollination occurs
when pollen grains from the anther settle on the stigma (plants are able to self pollinate)
cross pollination
when pollen from one plant settles on the stigma of another plant
mendels first accomplishment
produced true breeders (pure for one color)- allowed the purple plants to self pollinate for several generations (these true breeders would be called the P/parent generation
F1 generation
when mendel cross pollinated the purple true breeders with white plants it produced the F1 generation with all purple plants
F2 generation
let the F1 generation self pollinate and the result is the F2 generation- with 3 purple and 1 white
