1.	What type of crosses were carried out by Morgan on Drosophila?(a) Monohybrid(b) Dihybrid(c) Bihybrid(d) TrihybridI have been asked this question in an interview for internship.The doubt is from Inheritance Principles in section Principles of Inheritance and Variation of Biology – Class 12
Answer» CORRECT choice is (b) Dihybrid Explanation: Morgan was trying to observe the phenomenon REPORTED by Mendel. Hence, he did dihybrid crosses on DROSOPHILA. These dihybrid crosses allowed him to understand the process of meiosis. He also identified the phenomenon of linkage. This was used later by his student to CREATE the first genetic map.
