Question

Sutton and Boveri explained Mendel’s laws using ___.

• A. Movement of chromosomes during cell division
• B. Movement of nuclei during cell division
• C. Movement of cell organelles during cell division
• D. Movement of proteins during cell division

Answer 1

The correct option is A

Movement of chromosomes during cell division

Sutton and Boveri noted that the behavior of chromosomes was parallel to the behavior of genes, and used chromosome movement during cell division to explain Mendel’s laws. Sutton and Boveri argued that the pairing and separation of a pair of chromosomes would lead to the segregation of a pair of factors they carried. Sutton united the knowledge of chromosomal segregation with Mendelian principles and called it the chromosomal theory of inheritance.
