Compare in any three ways the chromosomal theory of inheritance as proposed by Sutton and Boveri with that of experimental results on pea plant presented by Mendel.

(a) Explain linkage and recombination as put forth by T.H. Morgan based on his observations with Drosophila melanogaster crossing experiment.
(b) Write the basis on which Alfred Sturtevant explained gene mapping.

Explanation

Chromosome theory of inheritance proposed by Sutton and Bovery :
1. They said that chromosomes are linear structures with genes located at specific sites.
2. It states simply that chromosomes which are passed from one generation to the next.
3. Over a period of time, random mutation creates changes in the DNA sequence of a gene.
Theory correctly explains the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes with the paired factors (particles) required by Memdel's Laws.
