Who observed that the behaviour of chromosomes at meiosis can serve as the cellular basis of both segregation and independent assortment?

Options:

Answer:
A
Solution:

The Boveri–Sutton chromosomal theory of inheritance is a fundamental unifying theory of genetics. It identifies chromosomes as the carriers of genetic material. It correctly explains the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes with the paired factors (particles) required by Mendel's laws. It also states that chromosomes are linear structures with genes located at specific sites called loci along with them.

The theory states that chromosomes, which are seen in all dividing cells and pass from one generation to the next, are the basis for all genetic inheritance.

Sutton and Boveri observed that the behaviour of chromosomes at meiosis can serve as the cellular basis of both segregation and independent assortment.
