Gregor Mendel

Gregor Mendel, often referred to as the Father of Modern Genetics, conducted pioneering experiments using pea plants, which became the foundation for understanding genetic inheritance.

Gregor Mendel

Independant Assortment

Experimented using Pea Plants

True-breeding
Testcross
Model Organism
many varieties and distinct traits
easy to work with
large number of progeny (offspring)
Quick life cycle

Principle of Segregation

Father of Modern Genetics

Principles of Heridity

Four Postulates

the two alleles seperate with equal probability into gametes
Concept of dominance
Recessive
Dominant

Co-dominance

Complete

Incomplete

Two alleles in each plant seperate when gametes are formed one allele in each gamete
Hemizygous
Each plant must possess two genetic factors encoding a character.
Complementation
Epistasis

Dominant Epistasis

Recessive Epistasis

Hypostatic gene

Expresstivity
Penetrance
Multiple alleles
