Alleles of different genes that are on the same chromosome may occasionally be separated by a phenomenon known as

Which of the following represents the frequency of recombination between two genes that are inversely proportional to the strength of linkage?

Total number of linkage groups in honeybee is . . . . . . .

Sex-linked inheritance was discovered by

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 be:
