Choose the correct answer from the options given below: 

(A) -(II), (B) -(III), (C) -(I), (D)- (IV)

The correct answer is Option (2) – (A) -(II), (B) -(III), (C) -(I), (D)- (IV)

A. Sutton and Boveri independently formulated the chromosomal theory of inheritance, which proposed that genes are located on chromosomes and that the behavior of chromosomes during meiosis explains inheritance patterns.

B. Gregor Mendel is known as the "Father of Genetics." He discovered the fundamental laws of inheritance, which include the principles of segregation and independent assortment, through his experiments with pea plants.

C. It was Thomas Hunt Morgan, who studied fruit flies and provided the first strong confirmation of the chromosome theory as proposed by Boveri and Sutton. Using fruit flies as a model organism, Thomas Hunt Morgan and his group at Columbia University showed that genes, strung on chromosomes, are the units of heredity. They showed that chromosomes carry genes, discovered genetic linkage - the fact that genes are arrayed on linear chromosomes - and described chromosome recombination.

D. Alfred Sturtevant used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes and ‘mapped’ their position on the chromosome. Today genetic maps are extensively used as a starting point in the sequencing of whole genomes as was done in the case of the Human Genome Sequencing Project.
