Morgan carried out several ________in Drosophila to study genes that were_______
1 Trihybrid crosses, sex-linked
2 Monohybrid crosses, sex-linked
3 Dihybrid crosses, sex-linked
4 Dihybrid crosses, autosomal-linked
Explanation:
Morgan carried out several dihybrid crosses in Drosophila to study genes that were sex-linked.

Fruit flies are one of the best materials for genetic studies because of all, except
1 Ability to grow on simple synthetic medium in the laboratory
2 Short life span
3 Production of a large number of progeny in each mating
4 Presence of few externally visible and identifiable contrasting traits
Explanation:
Drosophila melanogaster which were found very suitable for such studies. They could be grown on simple synthetic medium in the laboratory. They complete their life cycle in about two weeks, and a single mating could produce a large number of progeny flies. Also, there was a clear differentiation of the sexes – the male and female flies are easily distinguishable. It has many types of hereditary variations that can be seen with low power microscopes.

“Recombination” This term is used to describe
1 Generation of parental gene combinations
2 Generation of parental and non-parental gene combinations
3 Generation of non-parental gene combinations
4 None of them
Explanation:
The term recombination to describe the generation of non-parental gene combinations
