Milestones in Genetics and Genetic Inheritance February 16, 2001

Between 1860 and 1870, Austrian scientist Gregor Mendel proposed the concept of hereditary factors based on pea hybridization experiments and formulated Mendel’s laws of inheritance.

In 1909, Danish botanist Wilhelm Johannsen expanded upon Mendel’s theory and first coined the term “gene.”

In 1944, three American scientists isolated bacterial DNA (deoxyribonucleic acid) and concluded that DNA is the material basis for carrying genetic information.

In 1953, Americans James Watson and Francis Crick, through experimentation, proposed the double-helix molecular structure model of DNA.

In 1969, scientists successfully isolated the first gene.

In 1990, the International Human Genome Project, often referred to as the “Apollo moon landing” of life sciences, was launched.

In 1998, world-renowned geneticists in Rockville, USA, formed the Sequencing Corporation, competing against the Apollo International Human Genome Project.

In December 1998, the genome sequence of a small nematode was completed.

In September 1999, China was approved to participate in the Human Genome Project, responsible for sequencing 1% of the human genome. China became the sixth country to join the project, following the United States, the United Kingdom, France, Germany, and Japan, and ahead of Russia.

In December 1999, the International Human Genome Consortium announced that the genetic code for the 22nd pair of human chromosomes had been deciphered.

On April 6, 2000, the Sequencing Corporation announced that the sequencing of the 21st pair of human chromosomes had been completed.

In May 2000, Germany, Japan, and other countries announced that they had deciphered the sequencing of the 21st pair of human chromosomes.

In June 2000, scientists released the complete map of the human genome.

In December 2000, the United States, the United Kingdom, and other countries announced that they had deciphered the complete draft of the Arabidopsis thaliana genome.

On February 12, 2001, the United States, the United Kingdom, France, Germany, Japan, and China jointly announced that they had deciphered the complete draft of the human genome.
