MCQ on Chromosomal Basis of Inheritance

Sutton and Boveri proposed the Chromosomal Theory of Inheritance, which states that chromosomes are the carriers of genetic information. Neither Mendelian genetics nor gene linkage are completely accurate; rather, chromosome behaviour involves segregation, independent assortment, and, on rare occasions, linkage.
