He coined in 1888 the term "chromosome" to describe them. [1] [2] Among his many other anatomical and embryological studies, Waldeyer became known for his pioneering research on the development of teeth and hair, many of the terms he invented are still in use today. He also published the first embryological, anatomical and functional studies ...
Thomas Hunt Morgan discovered sex linked inheritance of the white eyed mutation in the fruit fly Drosophila in 1910, implying the gene was on the sex chromosome. In 1910, Thomas Hunt Morgan showed that genes reside on specific chromosomes. He later showed that genes occupy specific locations on the chromosome.

From this, he recovered an acidic substance which he called "nuclein". [1] 1880–1890: Walther Flemming, Eduard Strasburger, and Edouard Van Beneden elucidate chromosome distribution during cell division. 1889: Richard Altmann purified protein free DNA. However, the nucleic acid was not as pure as he had assumed. It was determined later to ...
The chromosomes are packed within the nucleus in complex with storage proteins called histones to form a unit called a nucleosome. DNA packaged and condensed in this way is called chromatin . [ 51 ] : 4.2 The manner in which DNA is stored on the histones, as well as chemical modifications of the histone itself, regulate whether a particular ...
Wilson, who was Sutton's teacher and Boveri's friend, called this the "Sutton-Boveri Theory". Between 1902 and 1904 Theodor Heinrich Boveri (1862–1915), a German biologist, made several contributions to chromosome theory in a series of papers, finally stating in 1904 that he had seen the link between chromosomes and Mendel's results in 1902 ...
Hermann Paul August Otto Henking (16 June 1858 – 28 April 1942) [1] was a German cytologist who discovered the X chromosome in 1890 or 1891. The work was the result of a study in Leipzig of the testicles of the firebug (Pyrrhocoris apterus), during which Henking noticed that one chromosome did not take part in meiosis.
Édouard-Gérard Balbiani (1823–1899), French embryologist who found chromosome puffs now called Balbiani rings; David Baltimore (born 1938), US biologist, Nobel Prize for the discovery of reverse transcriptase; Guido Barbujani (born 1955), Italian population geneticist and evolutionary biologist
