Timeline of Major Discoveries related to Genetics
1840s – Discovery of chromosomes.
1859 – Darwin publishes on the Origin of Species.
1865 – The laws of inheritance by Mendel.
1868 – Friedrich Miescher discovers DNA and RNA.
1905 – Discovery of sex chromosomes.

of certain nitrogen bases in DNA always occurs in a 1 to 1 ratio which forms base pairs.
