Gregor Mendel
Four Postulates
Each plant must possess two genetic factors encoding a character.
Multiple alleles
Penetrance
Expresstivity
Epistasis
Hypostatic gene
Recessive Epistasis
Dominant Epistasis
Complementation
Two alleles in each plant seperate when gametes are formed one allele in each gamete
Hemizygous
Concept of dominance
Dominant
Incomplete
Complete
Co-dominance
Recessive
the two alleles seperate with equal probability into gametes
Father of Modern Genetics
