WebThe chromosomal theory of inheritance was given by Boveri and Sutton in the early 1900s. It is the fundamental theory of genetics. According to this theory, genes are the units of … WebThe Chromosomal Theory of Inheritance was consistent with Mendel’s laws and was supported by the following observations: During meiosis, homologous chromosome pairs migrate as discrete structures that are independent of other chromosome pairs. The sorting of chromosomes from each homologous pair into pre-gametes appears to be random.
The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 and 1903, as well as to independent work by Theodor Boveri during roughly the same period. Boveri was studying sea urchins, in which he found that all the chromosomes had to be present for proper embryonic development to take place. Sutton's work with grasshoppers showed that chromosomes occur in matched pairs of maternal and paternal chromosomes which separate during meiosis a… WebSutton developed this hypothesis in “ The Chromosomes in Heredity” (1903) and concluded that chromosomes contain hereditary units and that their behaviour during meiosis is random. His work formed the basis for the chromosomal theory of heredity. This article was most recently revised and updated by Erik Gregersen. chromosome Table of Contents
