Detailed explanation-1: -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.
Detailed explanation-2: -chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 and 1903, as well as to independent work by Theodor Boveri during roughly the same period.so answer is option A.
Detailed explanation-3: -The Chromosomal Theory of inheritance, proposed by Sutton and Boveri, states that chromosomes are the vehicles of genetic heredity. Neither Mendelian genetics nor gene linkage is perfectly accurate; instead, chromosome behavior involves segregation, independent assortment, and occasionally, linkage.
Detailed explanation-4: -Walter Sutton and Theodor Boveri proposed the chromosome theory of inheritance (i.e, chromosomes are physical basis of heredity) after observing that the behaviour of chromosomes was parallel to the behaviour of genes predicted by Mendel. Watson and Crick proposed the double helical model of DNA.
