The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 [5] and 1903, [6] as well as to independent work by Theodor Boveri during roughly the same period. [7] Boveri was studying sea urchins, in which he found that all the chromosomes had to be present for proper embryonic development to take place. [8]
Walter Stanborough Sutton (April 5, 1877 – November 10, 1916) was an American geneticist and biologist whose most significant contribution to present-day biology was his theory that the Mendelian laws of inheritance could be applied to chromosomes at the cellular level of living organisms. This is now known as the Boveri–Sutton chromosome ...
Segregation and independent assortment are consistent with the chromosome theory of inheritance. When the parents are homozygous for two different genetic traits (llSS and LL s P s P), their children in the F 1 generation are heterozygous at both loci and only show the dominant phenotypes (Ll S s P).
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 .
Gene maps help describe the spatial arrangement of genes on a chromosome. Genes are designated to a specific location on a chromosome known as the locus and can be used as molecular markers to find the distance between other genes on a chromosome. Maps provide researchers with the opportunity to predict the inheritance patterns of specific ...
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 (although this is not documented in his publications).

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
