Define/Explain: Linkage.

The tendency of genes to remain together during the process of inheritance is known as

Select the incorrect statement$(s)$ from the options given below with respect to dihybrid cross.
$I.$ Tightly linked genes on the same chromosome show higher recombinations.
$II.$ Genes far apart on the same chromosome show very few recombinations.
$III.$ Genes loosely linked on the same chromosome show similar recombinations.

State the conclusions drawn from Morgan's experiments on linkage and recombination.

In the progeny of a dihybrid cross,the frequency of parental combinations is higher than that of non-parental combinations. This is due to:

Who performed the first experiment on linkage and recombination?
