About Gregor Mendel
Early Years
Successes
- Got high marks in school
- Was accepted into the University of Olomouc
- His family was poor
- He spoke a different language at home than he did at school
Experimental design
Cross different pea plants with different characteristics randomly and document what happens.
Fact or Example
- The dominant gene will always show through
- If you cross a red, sweet apple and a green, tart apple you will most likely end up with a red, tart apple.
Data
Specific Data
1. Mendel crossed a yellow seeded plant and a green seeded plant and it came out with a yellow seeded plant
2.He crossed two of the new yellow seeded plants and got a couple of green plants
3.Two of the new green plants could not make a yellow plant
What this means
The yellow gene is dominant but the green gene is still there. So, when you crossbreed a yellow and green plant you will always get a yellow plant but if you cross the new green and yellow plants there is a chance you will get a green plant instead of a yellow plant.

Foundation
Vocabulary
Definition: A gene that will overpower another gene
Example: In Mendel's experiment the yellow was the dominant gene so it showed over the green.
Recessive
Definition:A gene that gets covered up by another gene
Example: In Mendel's experiment the green was the recessive gene so it got covered up by the yellow gene.
CoDominant
Definition:A gene that is neither dominant or recessive (Both genes would show up)
Example: Some flowers have a codominant trait in them so they will have two colors in the pedals.
