BL 100: INTRODUCTORY CELL BIOLOGY
AND GENETICS
Lecture 6: Mendelian Monohybrid Inheritance
(Segregation)
, Gregor Johann Mendel
(1822-1884)
"father of modern genetics"
, Gregory Mendel
• 1st scientist to develop the fundamental principles
that became the modern science of “genetics”
• Mendel study was based on simple patterns of
inheritance
• Demonstrated that heritable properties are parceled
out in separate units (independently inherited)
• When doing his works, was selective growing the
common pea plants (Pisum sativum)
• At the time there was no knowledge of chromosomes,
DNA , cell structure, fertilization, mitosis and meiosis,
which were discovered after his lifetime
, Mendelism vs Darwinism
• In 1865 Mendel proposed that invisible internal units
(factors) of information account for observable traits
• These "factors" - which later became known as genes
• Mendel's work remained unnoticed, languishing in the
shadow of Darwin's more sensational publication from
five years earlier, until 1900, when Hugo de Vries,
Erich Von Tschermak, and Carl Correns published
research corroborating Mendel's mechanism of
heredity.
