Laws Of Inheritance
Gregor Mendel experimented with the genetics of pea plants for eight years (1856 - 1863). Through his experiments he discovered genetic similarities among pea plants. He published his findings in 1865. Mendel's experiments are known as the Laws of Inheritance. -
Centrosome
Boveri discovered the centrosome, which is the main microtubule organizing center of an animal cell. It also serves as the regulator of cell progression in an animal cell. -
Walter Sutton
Discovered chromosomes make up the basis of heredity, and in meiosis, the reduction of chromosomes relates to Mendel's laws of inheritance. -
Sutton and Boveri
Present findings that chromosomes are related to factors in heredity relating to the work of Gregor Mendel. -
Embryonic Development Needs
Theodor Boveri studied sea urchins to find out that having all chromosomes present is necessary for the development of an embryo to take place. -
Chiasmatypie
Frans Janssen discovered that genes cross over during meiosis. -
Thomas Hunt Morgan
Developed ideas, and brought together proof of heredity, genetic linkage, chromosomal crossing over and non-disjunction. -
Transposition
Barbara McClintock developed the theory for transposition, the position change of genes on chromosomes. -
Expression and Suppression
McClintock discovered/developed to understand the expression and the suppression of genetic information through generations. -
Double Helix
Crick and Watson find the molecular structure of dna called the double helix -
Crick RNA
Francis Crick finds adn reveals the use of messenger rna which transports genetic information.
