A Cytological Study Of The Salivary Gland Chromosomes Of The Attached-X Variety Of Drosophila Melanogaster, Jack Schull
A Cytological Study Of The Salivary Gland Chromosomes Of The Attached-X Variety Of Drosophila Melanogaster, Jack Schull
Bachelors’ Theses
The detailed study of -the salivary chromosomes of the Diptera has been of great importance in substantiating cytologically the theories of genetics. A noteworthy example of the importance of cytological study is the non-disjunctive phenomenon which has occurred on at least several occasions in the strain of Drosophila melanogaster. Bridges (1913) was the first to report nondisjunction of sex chromosomes which was an important confirmation of the chromosome theory. L. V. Morgan (1922) used the cytological study of the germ cells of Drosophila melanogaster to prove that there was no disjunction of the sex chromosomes in the attached-X strain.
