Mendel's 7 characteristics of the Garden Pea
Transcript of Mendel's 7 characteristics of the Garden Pea
Mendel's Garden Pea
Dominant trait would be a capital T and the recessive trait would be a lower case t.
Full pod shape is completely dominant to constricted pea pod shape
Immature pods may differ in shape from mature ones
Dominant trait would be represented as capital Y and recessive trait would be lower case y.
Round - R ; Wrinkled - r
Garden Pea plants were used to
study how traits were passed from one generation to another
reveal the presence of dominant and recessive traits in final generations
Dominant traits are inherited & unchanged from one generation to the next
Recessive traits disappear in the filial generation but reappear in the second filial generation at a ratio of 3:1 dominant: recessive
Filial- generations after the parental generation
Tall or Dwarf
Constricted or Inflated
Round or Wrinkled
Axial or Terminal
Tall- T ; Dwarf- t
When Mendel crossed homozygous tall plants with homozygous short plants, all the peas from these plants produced tall pea plants in the next generation
Dominant Trait would be represented as capital I and the recessive trait would be lower case i.
Inflated- I ; Constricted- i
Yellow - Y ; Green - y
Dominant trait would be a capital R and the recessive trait would be the lower case r.
The round seeds have higher starch content and so are used to make pea soup. The wrinkled seeds have higher sugar content and so are used as a fresh, frozen, or canned vegetable.
Axial - A ; Terminal - a
A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in
offspring with purple flowers, which demonstrates dominance.
Purple - P ; White - p
The dominance trait would be represented as a capital P and the recessive trait is represented as a lower case p.
Yellow - G ; Green - g
Dominant trait is represented with a capital G and the recessive trait is represented with the lower case g.
Dominant trait is represented with a capital A and the recessive trait is represented with the lower case a.
An axial position would grow with leaves going up and flower to the side, while the terminal would grow with nothing but flowers at the top.
