Linkage in Drosophila was first discovered by
Morgan
Bateson and Punnet
Sturtevant
Bridges
It's Obvious
The experiment shown in the given figure has been carried out by Morgan to show the phenomenon of linkage and recombination. If in cross $I$, genes are tightly linked and in cross $II$, genes are loosely linked then what will be the percentage of recombinants produced in cross $I$ and cross $II$ respectively?
The four daughter cells derived from a single meiosis differ from each other due to
The map distance between genes $A$ and $B$ is $3$ units, between $B$ and $C$ $10$ units and between $C$ and $A$ $7$ units. The order of the genes in a linkage map constructed on the above data would perhaps be
When two genes are situated very close to each other in a chromosome
The percentage of crossing over will be more if
