Genetic map is one that
Shows the stages during the cell division
Shows the distribution of various species in a region
Establishes sites of the genes on a chromosome
Establishes the various stages in gene evolution
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
Discuss in detail the contributions of Morgan and Sturtevant in the area of genetics.
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?
Crossing over in diploid organism is responsible for
In Drosophila, long wing and broad abdomen characters are dominant over to characters vestigeal wing and narrow abdomen. A pure breeding Drosophila having long wings and broad abdomen is crossed with a pure breeding vestigeal-winged and narrow-abdomened Drosophila. Two of the $F_1$ individuals were crossed and the following results were produced in the $F_2$ generation Long wing, broad abdomen in $482$ Drosophila. Vestigeal wing, narrow abdomen in $154$ Drosophila. Which one of the following is illustrated by these results
