Boveri and Sutton's chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance. Thomas Hunt Morgan, who studied fruit flies, provided the first strong confirmation of the chromosome theory.
Oct 31, 2023 · The 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 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 heredity and are found in the chromosomes. Chromosomal Theory of Inheritance came into existence long after Mendelian genetics.

The chromosome theory of inheritance, or the idea that genes are located on chromosomes, was proposed based on experiments by Thomas Hunt Morgan using Drosophila melanogaster, or fruit flies. Drosophila are like humans in that an individual with two X chromosomes is female and an individual with one X and one Y chromosome is male (many ...
Connection for AP. ®. Courses. Proposed independently by Sutton and Boveri in the early 1900s, the Chromosomal Theory of Inheritance states that chromosomes are vehicles of genetic heredity. As we have discovered, patterns of inheritance are more complex than Mendel could have imagined. Mendel was investigating the behavior of genes.
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]
