- Bateson and Punnet identified the notion of linking in the sweat pea plant, Lathyrus odoratus, in 1906.
- However, Thomas Hunt Morgan proposed the concept of linkage in 1910, based on his Drosophila melanogaster experiment.
- It has 4 linkage groups, that is, the number of chromosomes that form the genome.
Final answer: Number of linkage groups in drosophila are 4.
