Which of the following statements is false regarding linkage?

$A$ cross is made between two homozygous individuals, one with the wild type $(+, +)$ and the other with the mutant type $(a, b)$. In the $F_2$ generation (or test cross progeny), out of $1000$ individuals, $700$ are parental types. Calculate the distance between genes $a$ and $b$.

Who performed the first experiment on linkage and recombination?

Select the correct statement from the ones given below with respect to dihybrid cross.

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